    My Vartarg has a #3 contour 22.5" 1:12 twist barrel. It is a hammer with 32 sierra's, 32 V-Max or 32 Nosler ballistic tips. It also shoots 35 Bergers and 39 Sierra BK's well, but does not like the 40 V-max. If I was to build another one, the only thing I would change is to go to a 1:11 twist just to be able to use a larger variety of 40-45 gr pills for the occasional coyote. But the 32's work great on the smaller vermin and provide exceptional consistent accuracy even from a carry rifle.

    Gotcha...sound about perfect..I love the AI cartridges and the fact there is less case trimming is definitely a plus..I freaking hate trimming cases..it's the only step in reloading that I can't stand..time consuming and boring as heck..
    Thanks for the info

    The .20-223AI has about the same case capacity as a .20PPC, i went this way simply because of the cost of the brass, about .30cents a piece less for the Lapua 223 than the 220 russian....

    Can some one post case capacity for
    .20 vartarg
    .20 / 223 AI
    .20 ppc
    Just curious..I think the .221 fireball case is efficient with any bullet that is stuck in the case.
    What is the point of burning more powder if it's not needed

    If you are leaning towards the 221 case, check with Wirelessguy on here about his 20SCC...a 20VT on steroids basically.

    From a database published on Saubier -
    20 VT - 23.3 grains of water
    20 Tactical (similar to 223 AI?) - 30.2
    20 ppc - 33.5.

    Hey guys, just got back from a trip in north dakota. First time shooting 32 v-max at prairie dogs out of my vartarg. Did not find the bullets to be as explosive on target as I expected. Are the sierra blitzkings better at acrobatics than the v-maxes or do they have to be pushed faster a la 204 ruger? Are the 39's any better on prairie dogs?

    Here is every 20 cal case capacity you could ever need.

    What would be the best brass to use with a .232 chamber that doesn't require neck turning? I do not want to buy a $100 tool just to neck turn for one rifle, thanks

    Remington or contact Ramos over on smallcaliberclub.com or saubier he makes brass from LC. Bobcat is right you should check out the 20SCC.

    As has been said, why potentially limit yerself in future bullet choice with a twelve. Per B. Litz, 5fps loss of velocity for the inch of twist....a non event.
    You'll lose more than that with 10° temp drop.
    Per me, more twist, therefore rpm can only aid the splat factor.:cool:
    One thing I've learned over the years is to have as many options available as possible, seeing as how my crystal ball has been on the fritz since my late 20s.;):rolleyes:
    My 20-222 reamer has a .2355" neck.
    Lapua should be no turn. Spinning it up this Fall at my SC Bud's shop.

    for a shorter barrel (18-22") in a VT, would a 1-8 twist be better, or stick with an 11" twist?

    Twist doesn't have anything to do with barrel length. It is the weight and actually length of the bullet that determines the twist you go with. If you only plan to shoot 32 grain bullets, go with a 12 twist. Want to shoot or think you will shoot 40 grain bullets, better go with an 11 or 10 twist. Only if I planned to shoot 50 or 55 grain bullets would I go with an 8 twist in that caliber.

    depending on what I can get, will be the choice of bullets.. there isn't many/2 GS around here and they don't carry 20 cal stuff.
    I'll have to order off the web, and since there are hoarders out there... what is left will be my choice.


    I am waiting on the reamer ordered 20-221 AI (20 fireblaster) which should be 3 weeks out, or sooner.
    I have the Rem 700 221FB action, McMillian/Bruno lv edge stock, BA trigger, Leu. Vx3 6.5-20 VH scope.. just need to get a barrel on order reason for asking.

    Thanks for replies.

    3 20 vt here and all are 12 twist. They all shoot 39 and 40 gr bullets just fine. They also shoot 32 and 35's. One is a 24" cooper varminter , one is a 24" Shilen varmint contour on a Savage action and one is a ER Shaw. The Shaw barrel started as a 24" sporter that I had cut to 20" and threaded for a can. I shot a 5 shot group at 100 yds that I can cover with a dime with 39 gr sbk. (with the can). When I went from 24" to 20" I lost about 50-75 fps with 39 gr bullets when using H4198.

    I went with a 11 twist in my vartarg. shoots both the 32 gr and 39 gr sierras great. If you only want to shoot 32 gr bullets go with the 12 twist. if you want to shot 39gr and 40gr bullets go with the 11 twist. although the 12 twist will stabilize 39gr, the 11 twist does a better job of stabilization.

    24 inch twelve twist here. Shoots 32 and 35's outstanding. I'd say it's a little light for big old eastern chucks but certainly will do the job. It's perfect for pd's

    I'm very surprised you didn't find the results with the 32's outstanding. Been using them for couple years now for pd's. Very impressed. Tried to attach a pic but was too big

    Compared to a .223 55 gr SBK it was very tame. Thinking AA2200 and more velocity will improve splat factor.
