Not sure if this is the best section in which to ask this, but here goes.
What range of bullets weights should produce the best accuracy at .223 velocities in a 9" and 12" twist barrel, respectively?
Thanks.
Paul

Hey, Ingwe, have you used 60 gr NBT's in a 1 in 12?

No doubt good in a 1 - 7, mine is a 1 - 12 No. 1V. Was loading 64 BSB's for Bambi this year and loaded a few 60's to test. Saw the Poobah's post and thought I'd ask. 60's would be for coyotes or, heck, just for fun.

3 pigs fell to the 75 grain Swift last year, 1 10 point to the 62 grain TSX the year before. Of course some know nothing will post "the 70TSX is what you need" to which those who actually shoot animals will respond 53 grain tSX works just fine on deer, aim for the shoulder.

Mostly targets/fun.
Not one gun, two bolt rifles.
Don't have a 1-7, so not relevant for me. Want to start on the right track with each, so I don't have to try too many different bullets, scarce and $$ as they are.

52's will most likely shoot great out of both of them.

Consider weight after length. Longer needs a quicker twist. Often heavier is longer, but that doesn't always hold true.....like in the case of the 70 Speers.

I don't get as serious about twist as some of you but when Ingwe says he shoots 60's out of a 1/12 and Mike NZ says 70 Speers will stabilize in a 12" twist, why would you want a 1/7 or 1/8? I'm thinking a 1/9 or 10 would be more than adequate and middle of the road.
I know the Army went to a 1/7 about 30 years ago but that was to shoot 62 grain steel core bullets. I do have one rifle that is a 1/8 but it does not shoot any better than one I have a 1/10 both shooting 60 grain Hornadays. Both rifles are completely different so that might be why.
I guess that's why we have a forum to discuss things like this. To each his own.

I just have 1-7's as that is what is usually provided with a 5.56 chamber. Thus you can get a scooch more powder in the case. I have had 1-12, 1-9, 1-7, and 1-12 would definitely keyhole ss109 greentip.

kwg Probably because they don't charge more for the 1-7 over say a 1-9? SOME bullets that you'd not think would stabilize in the 1-10/12 twist do but not all of them. With a 1-7 - you get all of them.

50 gr v-max should work very well in either barrel. I've shot them out of 1-12 bolt gun and 1-7, 1-8 and 1-9 AR's, as well as a 1-14 221 f-ball. Very accurate in all the barrels.
