Ok boys, I got the gun (CZ527..) got the dies..everything I need to get going..I have load data from Sierra but, I would like to know what the guys that shoot the gun and reload use. I have a friend that has bullets from 40grs up to 52grs. So tell me what you use...primer, powder, bullet.
I have H4227 but will try what the concensus uses..(well maybe not but would like to hear it from the guys that shoot it) Thanks

Glad you got the rifle. I'm seriously considering a Cooper in 221 Fireball, so did a bit of poking around this weekend and found this article:

The 40 grain at 3600 fps with Lil' Gun looks like one to try.

P.S. 221 brass is back in stock at all the usual suspects.

My CZ 527 221 Fireball shoots just about everything well. I have tried quite a few powder/bullet combos and settled on 2400 with either 40gr Nosler BT or 40gr Vmax. They both shoot about the same. 2400 gives me excellent velocity and accuracy and my barrel stays much cooler than with other powders. Fast, accurate and cool, can't beat that.
CZ 527 221 Fireball, age 12, 100 yards 5 shot groups.

I don't post a lot on this forum but I will jump in on this thread.
I picked up my Fireball about a year and a half ago, Rem 700 Light Varmint Stainless Fluted, but changed out the synthetic stock for a Boyd's Thumbhole Laminate. The flimsy synthetic stock couldn't hold point of aim but the rigid stock is great. It adds some weight but well worth the trade off.
Back on topic, I had the same questions but didn't get a lot of help. What I found is this:
RL #7, IMR 4198, and LilGun powders all work well with Nosler 40 grain and 50 grain Ballistic Tip bullets. The Sierra BlitzKing 40 and 50 grain bullets are great too but I can buy Noslers in the bulk pack.
I worked with lots of different primers too, the only one I didn't like was the Federal 205 because accuracy suffered. CCI BR4, Rem 7 1/2, CCI 400 are my choices in that order.
The load I settled on as my go-to load for the Fireball uses RL7 powder and Rem 7 1/2 primers (7 1/2 is the primer most readily available to me so I thought I should have a good load for it) and the 40 grain Ballistic Tip bullet. RL7 is the most consistent (accurate) powder with 4198 a close second. The school is still out on my LilGun load. I see potential but - I ain't there yet. I like things simple so I use a 1.3cc Lee Dipper Cup to measure powder. It is right around 19 grains.
Both 50 grain bullets work well in the Fireball and they aren't quite as subject to wind drift but the 40 grain bullet is faster and it has performed tremendously on everything I have shot. Crows hate them!

IMR 4198 is the classic powder for this cartridge and it works as well now as it did 15 years ago. Since then RE7 has proven to be an exceptional powder for accuracy and velocity. My accuracy load shoots a 40gr bullet @ 3,200 ft/sec.
Three years ago I experimented with Lil'Gun in the 221 with the 40 gr bullets. Velocity gains are almost unbelievable. I shoot a 40gr BT (moly) bullet @ 3,600 ft/sec from my 21' Hart bbl. Accuracy is about .5moa @ 200 yds.
The load is a bit warm in my rifle but velocities of 3,400-3,500 ft/sec should be obtainable without much trouble in any rifle. Lil'Gun is very cost effective with typical charges being only about 16 grains.

Thanks so much for responding..I plan on useing this for pdogs in SD. I have a box of factory loads (50 grs) that I have yet to shoot, thanks to global warming...Had 3' of snow Saturday..wind...Not my idea of an ideal time..So I am leaning towards the RE-7..not sure on the bullet..I will be taking a 17HMR for the inside stuff, and a 243 for the outside.221 FB for the middle.If I sound stupid it may be that I am as I have Never gone PDog shooting.Guess I am a old newbie!

I am what you guys call a 'flat lander'. I live in the center of Long Island. It's a long ride for me to hunt almost anything other than whitetails with the bow. I travel to PA every week to hunt varmints.

I took my .221FB out to Casper Wyoming and had no problem splatting PDs at 300 yds. You will need very calm winds (none) to get any use out of the 17HMR. I love mine but its use is limited.

I know how that goes. I got a new gun over a month ago and just got the scope mounted last night and bore sighted it this afternoon. I also loaded up 20 rounds to take to the range and dial it in. Now I just have to get to the range and dial it in, probably this weekend.

I finally got to shoot today..I am disappointed to say the least. I get 1.5 inch groups with the factory ammo as well as handloads using 4198 from 17 up to 18.2 grains. Did not seem to matter. I did smoke a crow at 107 yards but I need to get these groups down..

I was at the range today myself. I took my new 223 and my Fireball.
It was dead calm and about 50 degrees. My Fireball load was 1.3cc Lee Dipper Cup (right at 19 grains) of IMR 4198, Remington 7 1/2 BR primer, Sierra 40 grain BlitzKing bullets. The brass was FL sized (it's the only sizing die I have) and bullets were seated to within .010' from the lands. I was printing one hole groups at 200 yards.
This photo was about two weeks ago, same load as above only with Nosler Ballistic Tip bullets, it was really windy that day. The photo should be rotated 90 degres right for the same orientation it was at the range. The cluster of shots should be to the left of center. The wind was intermittent and quite blustery. The target was set at 150 yards.
A question - I only get good groups when I snug the gun up tighly to my shoulder and hold the forearm of the gun with slight downward pressure onto the rest. This prevents muzzle jump and if all goes well I touch off the shot when the cross hairs are where I intend them to be. Is it possible you are relying on your rest to secure the front end of your gun? Even the Fireball will jump quite a bit when fired.

19.2, 19.3, 19.4 grs RL7 behind a 40 grain Nosler, F205M primer. Does 3150-3200 fps and shoots half MOA for 3 shots if I do my part. 5 shots not much bigger. Rifle is a CZ 527 American and scope is a Leupold VXII 3-9x40 LR duplex. My best load for the gun so far. Just testing to find out which powder charge seems to shoot the best!

The 20 CAL REVOLUTION
Before the first 20-Caliber factory cartridge (the .204 Ruger) appeared, 'Twenties' were not well-known to most shooters. Only some very dedicated varminters and die-hard Wildcatters played around with the 20 Caliber variants. Over the years, however, through the hard work of Todd Kindler of the Woodchuck's Den and other sub-caliber pioneers, 20-Caliber (and 17-Caliber) cartridges have become very popular. Today's small-caliber shooter finds a wide selection of barrels, bullets, reloading dies, and accessories. This guide covers five of the most popular 20-Caliber cartridges: .204 Ruger, Tactical 20, 20 PPC, 20 BR, and 20 VarTarg.

20 VarTarg | 20 PPC | 20 BR | Tactical 20 | 204 Ruger

6mmBR.com SPONSORS

20 Practical -- Easy, Accurate, Affordable Wildcat
You've probably heard of the '20 Tactical', Todd Kindler's 20-cal cartridge based on the .223 Remington necked down to 20 Caliber, with the shoulder modified to 30° and pushed back. You can buy 20 Tactical brass from Dakota Arms, or form your own cases.
But there's an even simpler 20-Caliber option based on the .223 Rem parent case--the 20 Practical, which is simply the .223 Remington necked to .204. The 20 Practical is the brainchild of Warren Brookman, who has shot it with considerable success in his bolt guns. Warren's 20 Practical rivals the .204 Ruger for velocity, and you can use your regular .223 Rem Redding Type 'S' dies. Just change out the bushing in your neck-sizing die, and substitute a different decapping pin assembly and expander button. All the details are explained in Warren's 20 Practical Feature Story.
20 Practical for the AR15 Platform
The 20 Practical is an ideal 20-caliber solution for AR15 platforms. The 20 Practical feeds and functions 100% reliably with standard AR15 magazines. No mechanical mods are required to your AR, other than a barrel change. You can start with .223 Rem brass, and just size down the necks with a neck-bushing die. It works best if you bring the necks down in two stages.
Robert Whitley has been developing a 20 Practical AR15 for us. Robert reports outstanding accuracy with both 32gr and 40gr bullets. Our prototype rifle is delivering 1/2-MOA or better accuracy with Berger bullets and H335 powder. Velocity is 3750 fps with the Berger 40-grainers in a 24' barrel, and the 32s will run 4000 fps with the right load. Other good powders for the 20 Practical are H4198, N133, H322, and Accurate 2460.
Shown below is Robert shooting an AR15 with a 20 Practical Upper. This rifle is fitted with a side bolt handle and GG&G forward scope mount. Robert's company, AR-X Enterprises, plans to produce similar 20 Practical AR15 uppers for sale; these should be available by September, 2008. As you can see, there is almost no recoil. With virtually no load development, Robert achieved excellent accuracy. In the video below you can see Robert shooting a five-shot group rapid fire.

Treatise for Twentiesby Kory Hamzeh, 6mmBR.com 20 Caliber Editor
Why are folks turning to the 'Terrific Twenties'? Among the most important reasons are: low recoil, high velocity, low noise, reduced cost, longer barrel life, and better ballistics for a given bullet weight. In short, compared to a .223 Rem, a Twenty shoots flatter, costs less to shoot, and is easier on the shooter's shoulder and his barrel.
The first time you shoot a 20-Caliber rifle, you'll note that there is minimal recoil, meaning the muzzle stays on target. No loud, dust-kicking muzzle brakes required here. You can shoot and actually 'see the show'. The rifle doesn't move enough during recoil for you to loose your target in the scope. This enables you to quickly asses the results and make a follow-up shot, if need be. A related advantage is low blast and noise. Even with relatively short barrels, 20-caliber rounds burn less powder than larger varmint cartridges such as the 22-250, and the Twenties make less noise. This definitely works to the hunter's advantage in a large field of ground squirrels or prairie dogs.
I'm often asked how a 20-Caliber gun compares with the ever-popular .223 Rem. Well, I tell people the Twenty is flatter-shooting, easier on barrels, and it is a better choice for small varmints, whether you want to 'mist 'em' or save the pelt.
The Velocity Edge--A .204 Ruger drives a 40-grainer 600 fps faster than a .223 Rem can push the typical 22-Caliber 50gr bullet. This higher velocity produces a flatter trajectory. Additionally, grain for grain, 20-Caliber bullets have higher ballistic coefficients than .224 bullets. Combine this with the extra velocity of the 20-Caliber, and you get superior performance in the wind. Run the numbers and you'll see--a 40-grainer shot from a .204 Ruger has less drop AND less wind drift than a 40gr or 50gr bullet fired from a .223 Rem. You'll find the data in the chart below.
Component Economy and Barrel Life--All the Twenties burn way less powder than a 22-250, and the smaller Twenties use less powder than a .223 Rem. This attribute actually has two advantages. First, it makes shooting 20-Caliber cartridges more economical, but mostly it means less barrel heat. A typical varmint hunter may shoot several hundred rounds in one day, so barrel heat is an important issue.
Terminal Ballistics--For hunters seeking maximum explosive effect on a small varmint, Twenties deliver the goods. Because it passes through the rifling much more quickly, a 20-Caliber bullet will be turning much higher RPMs than a 22-caliber bullet launched from a barrel of similar twist rate. Experienced varminters will tell you that high spin rates create the most explosive impacts. On the other hand, if you shoot a non-fragmenting bullet, the Twenty can minimize hide/fur damage. If you plan to keep the fur, you want the smallest possible hole or damage to it.

Bullet Selection
By far, the most popular 20-Caliber bullets are the factory-made pills from Berger, Hornady and Sierra. These are available in Flat-Base, Short Boat-tail, and Full Boat-tail designs in weights ranging from 30 to 50 grains. While most of these bullets are designed for varminting, many target shooters are using the 40-50 grain bullets with considerable success. A 12-twist will stablize most bullets up to 40 grains. After that you'll need a 1:11' or 1:10' twist. To shoot the Berger 50s, Berger recommends a 9-twist.

Which Bullet Should I Use?
How to show hard drive on mac desktop. Airmagic 1 0. When selecting bullets, the general rule of thumb is 'let the rifle decide what bullet it likes'. The forest free to play. Every rifle, powder, primer combination may shoot one brand of bullet or one weight range more accurately than another. As you change bullet weight, you may find that you need to change the brand to maintain accuracy. For example, as stated earlier, some rifles will shoot a Hornady 32gr V-MAX very well, but they won't shoot the 40gr V-MAX. However, the same rifle may like the Sierra 39 grain BlitzKing. You may also find that some brands may shoot very well, but only if you sort the bullets by weight or base to ogive length first. In our experience, nearly all factory bullets benefit from sorting.

The Hornady V-MAX bullets and the Sierra BlitzKing tend to be equally explosive and both fragment very well. We suggest you try both and use the brand that shoots better in your rifle. Although we have heard no complaint about the Berger bullets no being explosive enough, polymer tip bullets (Hornady and Sierra) tend to be more explosive than the Berger, but maybe not quite as accurate. The Berger 30gr and 35gr Flat Base bullets tend to fragment more than the 40gr or 50gr Berger Boat-Tails. True Boat-Tail bullets normally have less bearing surface area than Flat-Base bullets of the same weight. This means you can expect more velocity from a Berger 40gr LTB than the Hornady 40gr V-MAX or the Sierra 39gr BlitzKing.
Choosing the correct bullet weight will depend on the environmental condition and the size of prey. Lighter bullets shoot flatter and faster thus giving you longer range, however, they tend to drift more with wind than the heavier bullets. Likewise, heavier bullets drift less and have a bigger knockdown power, but you won't get the same kind of range from them. Most reloaders develop two loads: one with a fast, lightweight bullet for long range on calm days, and a slower but heavier bullet for windy days or larger varmints. We've compiled complete ballistics tables for the most popular Berger, Hornady, and Sierra Bullets, with drop and wind-drift calculated from 100 to 500 yards. We've run the ballistics for a range of start velocities, so you can compare different cartridges. Click Here to VIEW Ballistics Tables.
20-Caliber 'Boutique' Bullet-Makers

20-Caliber Barrels
Most barrel manufacturers produce 20-Caliber barrels. In fact, these days it's somewhat unusual to find a major barrel-maker that does not produce .204-bore barrels. With regards to twist rate, there aren't that many choices. Right now, it seems that only 1:9', 1:10', 1:11', and 1:12' twist rates are being manufactured. But the 9- and 11-twist are not made by all of the barrel makers. The 12-twist is the most popular and works very well with bullets up 40 grains. Some 12-twist barrels do seem to shoot the 40-grainers accurately, but that's probably at the edge of the stability envelope. Others have found that when the 40gr bullets will not stabilize, the Sierra 39gr BlitzKing bullets stabilize quite well in the 12-twist. For most bullets heavier than 40 grains, an 11-twist or 10-twist is recommended.

.204 Ruger
Introduced in 2004 by Hornady and Ruger, the .204 Ruger is the only 20-Caliber cartridge offered as factory-loaded finished ammunition. With 32gr bullets, Ruger claims the round is the fastest factory cartridge in any caliber. The .204 Ruger is based on the 222 Remington Magnum case, necked down to 20 Caliber. Currently, Hornady, Remington, and Winchester produce brass for this caliber. Because this cartridge is in large-scale production, it is the most popular of all of the 20-Caliber cartridges listed in this guide, even though it is the newest of them all.
The .204 Ruger isn't fashionably 'short and fat'. It bucks the trend in modern cartridge design. Nonetheless it delivers great performance and surprisingly good accuracy. Our friend Ken Lunde has a Model 21 Cooper MT Varminter chambered in .204 Ruger. With factory ammo, it shot slightly over half-MOA. With his handloads (Reloader 10X and Sierra 32gr BlitzKings), the Cooper delivers quarter-MOA 5-shot groups at 100 yards.
While low-profile cartridges like the 20 BR are normally more efficient than a tall and thin case, the .204 Ruger more than holds its own, speedwise, versus any of the popular 20-Caliber cartridges. The smaller diameter case-head gives it one important mechanical advantage over the larger diameter 20 BR--less bolt thrust. This means the .204 Ruger can be used in some very compact falling-block actions which are not suitable for cases with a .308-sized rim. The .204 enjoys one huge advantage over all the other popular twenties--the availability of factory ammunition. We reloaders may scoff at the idea of buying factory fodder, but it's nice to know that option is available, particularly on an extended varminting holiday.
WARNING: For your own safety, ALWAYS reduce all starting charges by 10% and work up carefully! Ambient temperature changes, powder lot variations, and differences in barrel friction can result in significantly increased pressures.

20 BR
The 20 BR is probably the fastest 20-Caliber cartridge in wide usage. There are some faster (20-250 and 20-220 Swift), but only a handful of experimenters have tried them. As the name implies, it is based on the 6mm Norma BR case, necked down to 20 Caliber. Most reloaders form the case by using a 22 BR die, but with a smaller bushing. The 20 BR is another super fast and accurate cartridge that is very popular with varmint hunters. Given the superb qualities of the parent Lapua 6BR brass, the 20 BR delivers outstanding accuracy with very little brass prep. The necking-down process can lead to brass-build-up in the neck-shoulder area. This is normally not a problem if your throat is set so that the base of the bullet is in the mid-neck area. Otherwise, inside reaming or outside neck-turning will solve the problem
Recently we talked with Todd Kindler about the 20 BR. He told us 'If you like the 6mm BR, you'll like the 20 BR even better.' He suggested we run the ballistics at 500 yards for a 50gr .204 Berger at 3900 fps. Well we did, using Point Blank software (with a 1000' altitude), and the results are shown below. The 105 Scenar has 5' less wind deflection, but the little 20 drops nearly two feet less. Conclusion: the 20 BR shoots flatter than a 6BR at 500 yards, and in calm conditions, it can really shine.

20 BR50gr Berger0.2963900 fps41.14'20.58'

At first, when looking at the specs, it may appear that the 20 BR is an overbore cartridge, but real life testing has proven otherwise. WarrenB (Fireball), an avid 20 BR shooter, states 'I really love my 20 BR. I have put around 500 rounds through it and my buddy's bore scope shows no real wear yet at the throat. The nice thing about the 20 BR is that it is so easy to push a 40gr. bullet at 4000 FPS with mild pressures. The recoil from the 20 BR is mild with a heavy rifle using a good bench-type stock. I think the sweet spot for the 20 BR is as a heavy, shoot from the bench, prairie dog rifle shooting 39 or 40gr bullets easily at 4000 fps on a hot day with no pressure worries. It is obviously very accurate as well. In terms of case-forming it is as easy--just buy 6BR brass and neck them down. I am using my existing 6mm and 22 BR dies to do everything. Only a new bushing was required.'
WARNING: For your own safety, ALWAYS reduce all starting charges by 10% and work up carefully! Ambient temperature changes, powder lot variations, and differences in barrel friction can result in significantly increased pressures.

20 PPC
The 20 PPC is the smaller brother of the 22 PPC and the 6mm PPC. All three PPC cartridges are based on the 220 Russian case. Initially, the 20 PPC was used mostly by varmint shooters looking for a high-speed, flat-shooting cartridge with exceptional accuracy. But the 20 PPC is finding a place among Benchrest Competition shooters, now that match-grade 20-Caliber bullets are becoming readily available. Running a 50gr Berger (.296 BC) at 3800 fps, the 20 PPC actually shows less wind drift than a 6mm PPC shooting 68-grainers at 3250 fps. 20 PPC shooters feels this gives them an edge in windy or rapidly switching conditions.
The 20 PPC is formed by using a 22 PPC die with a 20-Caliber bushing. Bushing size depends on your neck diameter and whether you have turned necks. For varmint shooting, neck turning is not worth the effort. Any accuracy advantage is negligible. But among competitive benchresters using the 20 PPC, most believe that a tight-necked chamber with turned necks will give you a slight edge. Once the brass has been necked down from .224 to .204, you'll need to fire-form it. There are various fire-forming strategies covered in our 6PPC Cartridge Guide. The simplest method is to use a full 220 Russian load from your powder-maker's data sheet, seat a bullet into the lands, and shoot. You may be surprised at the accuracy that can be achieved during fire-forming. Bob Smith reports excellent accuracy (.2 MOA or better) when fire-forming with his Lilja-barreled 20 PPC. And John (SnakeEye) of VarmintsForFun.com tells us: 'These 20s are a pleasure to shoot and load for. I am really pleased with the 40gr V-Max as it flat shoots very well out to 600 yards in my 20 PPC. Hornady did a fine job designing that bullet. What has amazed me is how well the 40-grainer shoots in my fast-twist barrel (Lilja 1:9') in the BAT Rifle. I use naked bullets and can shoot 30 to 40 rounds before I need to clean and there's hardly any fouling. There's practically no recoil and there is a noticeably reduced muzzle blast.'
WARNING: For your own safety, ALWAYS reduce all starting charges by 10% and work up carefully! Ambient temperature changes, powder lot variations, and differences in barrel friction can result in significantly increased pressures.

Tactical 20
The Tactical 20 was invented by Todd Kindler long before the .204 Ruger hit the market. Based on the .223 Remington parent case, the Tactical 20 is simply the .223 necked down to 20 Caliber with a 30-degree shoulder. Some versions have slightly less body taper as well--it's wise to compare reamer prints. Although the Tactical 20 has about three grains less case capacity than the .204 Ruger, it delivers very similar performance. With the right load, you can get Max velocities with 32- and 40-grainers that give up little or nothing to the .204 Ruger. Varmints probably won't know the difference. The Tactical 20 is easy to load and exceptionally accurate. Currently, Cooper Arms of Montana and Dakota Arms offer factory rifles in Tactical 20 chamberings.
Since the Tac 20's parent case is the ubiquitous .223 Remington, there is a huge selection of high quality brass available, limited only by your budget. Some precision shooters like to start with Lapua brass. The author has had excellent results using IMI brass, which is strong and very durable.

Best 221 Fireball Loads Vs


Forming 20 Tactical brass is generally a two-step process. You start with a 223 Remington brass that has been full-length sized in a .223 die. Then run the brass through a Tactical 20 forming die, and finally run it through a Tactical 20 full-length die. Case lubrication/wax should be used very sparingly just on the neck and the body. Too much lube will result in wrinkled shoulders. Although the wrinkles will blow out once the case is fired, they make the cartridge looks somewhat unattractive. The author has had great results using Redding dies with Hornady Unique Case Lube, while others prefer Imperial Sizing Die Wax. The Hornady Unique Case Lube is a little thinner, so it tends to be more forgiving if too much is used.
Some reloaders, like the author, will anneal the brass as the final step. Although not necessary, annealing tends to help the fire-forming process and extends the life of the brass a bit.
Lapua Tactical 20 Brass Is Here
Lapua-brand Tactical 20 brass has arrived in the USA, and is available through Dakota Arms, Graf & Sons and other retailers. Grafs.com list the brass as a Dakota Arms product, item # DU4HH5006, priced $39.99 per hundred. With the factory brass, Tac 20 shooters won't need their form dies anymore, and, in all likelihood, a separate fire-forming process will become superfluous. Or at least fire-forming will no longer change case capacity to the extent that you need a separate, slightly lower, fire-forming load.
WARNING: For your own safety, ALWAYS reduce all starting charges by 10% and work up carefully! Ambient temperature changes, powder lot variations, and differences in barrel friction can result in significantly increased pressures.

20 VARTARG
The 20 VarTarg (VARmint/TARGet) is another 20-Caliber cartridge designed by Todd Kindler for varmint hunting. This cartridge is based on the 221 Fireball case and is probably the most efficient of the 20-Caliber cartridges. It is also extremely accurate. Like the 6PPC, it has the optimal bore to case capacity ratio for max efficiency. The VarTarg is popular with varmint hunters because it provides good range (up to 300 yards) and uses relatively little powder, so your barrel doesn't heat up quite as fast. With the 20 VarTarg, long barrel life can be expected. Check out the Load Map below and you'll see that the diminutive VarTarg pushes the 32gr pills up into the 3750+ fps range with much less powder than is used by the .204 Ruger or 20 BR. The VarTarg achieves this performance by using fast, high-energy propellants, such as H4198 and Vihtavuori N120. Todd Kindler reports great accuracy with N120 and the Sierra 32-grainer, running close to 3800 fps. The VarTarg may be the smallest 20-Caliber cartridge in our survey, but it comes up big in efficiency. (Photo is 100% scale.) Currently, Cooper Arms of Montana and Dakota Arms offer factory rifles in 20 VarTarg. Click Here to download a .pdf version of Todd Kindler's 20 VarTarg article (from Dakota Arms).
No special dies are need to form 20 VarTarg brass. Simply run a .221 Fireball case through a 20 VarTarg full-length sizer die--then load, and shoot. There is virtually no difference performance-wise between virgin brass and fire-formed 20 VarTarg brass, so you don't need two different loads. Right now Remington is the only source of parent .221 Fireball brass. Most 20 VarTarg shooters are satisfied with the quality (and price), so long as the Rem brass is weight-sorted and prepped before loading. There was some hope Lapua would produce 20 VarTarg brass for Dakota Arms, but that deal is off the table. If there is enough consumer demand, Lapua might bring out 20 VarTarg or (more likely) .221 Fireball brass on its own--but don't hold your breath. John (SnakeEye) of VarmintsForFun.com hopes Lapua does produce 20 VarTarg brass: 'That will open up a whole new world in the little 20s. I've always thought that the 20 VarTarg would make a very accurate benchrest round with good brass. It seems to be a good combination of case capacity and bullet. Also this will be perfect for the 17 m 4 as all you would need to do is run it in a 17 m 4 FL die, no other forming.'
WARNING: For your own safety, ALWAYS reduce all starting charges by 10% and work up carefully! Ambient temperature changes, powder lot variations, and differences in barrel friction can result in significantly increased pressures.
