Whats the most accurate 20cal cartridge?

[skeetlee]

Just curious as to what you guys think is the most inherently accurate 20cal chambering? I am sold on the idea that the 20-222 is the king. Maybe i am wrong but it seems to me that it offers the best powder to bullet to size of case to magic ratio, that equals the best accuracy. I have a dear friend that is shooting the 20-222 and he is getting spectacular accuracy with it. anyone else shooting the 20-222? Give me your thoughts on all this. Lee

Lee,

I have had a 20BR, 204 , and have a 20TAC. I think the 20BR is very overbore. The 20 Tac has the great brass. It is great. But I think the 20 PPC would be the best, great brass, just add a barrel to a PPC.

No experience with the 20-222. From the testing we have done between, 20br, 204 ruger, 20 tac and 20x47 lapua, the 20 tac has proven to be the more accurate round.

While I don't own one, I've heard of spectacular results from the .20 VarTarg. I understand it is in that magical accuracy ratio too. It certainly has to be a contender.

Hands down 20 Vartarg.

Typical 20VT target.

With all the bitchin' and moanin' I read about the poor quality of 221FB brass, I'm suprised that any cartridge based on this brass is accurate at all. Maybe some of these bitchers are not so smart? My 20-222 is really accurate as is "The Bruiser" in 20PPC.

I have to agree with Doc,

20-222,20 Bobcat,20PPC and 20 Dasher are my only 20 cals......

The rest just don`t do much for me.....

ab - what do you use for source brass? Anything other than RP fireball brass would need a lot of forming. The two guys I know who shoot the VT get about 40-50 decent pieces of brass out of a lot of 100 Remington brass.

If Lapua made brass for the round you could get groups smaller than bullet diameter!

Otter it is not that hard to form up 20 Vartarg cases.First up run your 222 lapua cases through a Redding 221 form and Trim Die cut of the chimney then straight into a Hornady 20 Vartarg full length die with the expander button removed,Trim and neck turn.Nothing to it ;D

You might check over on Sauber.com, they do a lot of .20 cals there.
Also Todd Kindler's book Twenty calibers is an interesting read.
By the looks of it the Bullet and barrel quality is very good and they are able to get most of the .20 calibers to shoot in the 2's and 3's at 3700-4000 FPS.

This thread explains how I build my 20VT brass. ADam

Thanks for the link. Looks very easy. Would it be easier using .222 Rem brass or about the same?

(L461 - just saw your post so that answers my question.)

 

[TominSWNY]

Like every thing I can’t be sure that it is the most accurate 20 cal but it has me fooled. Thanks to the round Defiance action you sold me and a 9 twist 27 inch 6 fluted Pac-Nor barrel and an old Macmillan hunter stock converted from a flat bottom to fit the round Defiance action. This is the second 3 shot group fired like this. If the wind will stop blowing at 30 MPH and the rain lets up I may even be able to do it again.

My Cooper .20VT shoots consistent 1/4" MOA groups, without annealing, neck-turning, case weighing, etc. I use the plain-Jane Remington .221 Fireball brass and neck it down with a VT die. I would imagine that the rifle would print bench-rest accurate holes with some work on the cases, but I don't use the rifle for bench-rest. It is used at this time for ground squirrels. Cuts 'em in half with no muss. Love the caliber: hardly any barrel heat, easy on the barrel for long barrel life, hardly any recoil (you can see the bullet hit while looking through the 'scope), the case sips powder (around 17 gr), and the 32 gr bullet speeds fast enough so as to buck the wind. Nice little rifle. Definitely buy the Todd Kindler book for all the information you need to know.

I have a 20vt, 20 tac and 20 Duster, which is an improved 20-222. Havent shot the VT once since I got the duster, cant get rem 221 brass to shoot worth a hoot and havent had interest in forming from 222 yet. To keep one, would be the duster, can do just about everything the tac can do and absolutely everything a vt can do. Pushing 32vmax at 4000 fps with n133 with the duster. Won a local group match recently with that rifle.

 

[skeetlee]

what do you use for dies for the duster? sounds interesting. Lee

 

[RJinTexas]

I agree with Berry. First off no one is going to use any of 20 calibers for shooting bench rest. I have a 20 VT, 20 Tac, 204 Ruger and 20BR all of them will consistently produce mid .2's to low .3's.The 20BR & 20VT has produced a few high .1's. Like Berry my rifles they are used for shooting varmints so the last thing I want to do is spend the amount of time that would be required to form & neck turn several hundred cases needed to shot p-dogs. Just keep it simple and enjoy the great flat shooting light recoiling 20 calibers. Inside of 300yds I like the VT, from 300 yds out give me the slighly over bore 20 BR.

Barry and RJ - Thanks for the reality check. It would be mostly a varmint gun so the RP brass would be good enough. For the times I wanted to impress the guys at the range I could use 25 or so rounds of the better brass. Now I'm thinking I might just go for a 20 VT. The light recoil, low powder charge and fast bullets are hard to argue with.

 

[GrocMax]

For high volume varmints its hard to beat a 20 Practical, surplus WC844 ($85.00/8lb), relatively inexpensive new or once fired 223 brass, easy squeasy case forming, and bulk 34g 20 cal slugs from Midsouth (82 bucks/1000) flung at 4200 FPS. Point and click inside 350 yds.

You can form and load in one setup on a Dillon if you try, just move the powder to station #3.
