Would a 20in barrel create enough velocity to stabilze the 115 DTAC or any of the heavier bullets?
yes you would want a 8 twist
I am shooting the 6x47 lapua in a 18" 8t barrel and it will stabilize the 115s
so its more about twist rate than velocity, right?
yes it is about the twist to stabilize the bullets
are you building a XP or something else?
It's going to be a savage pta pistol.
Right on brother me too, mine is going to be a 6mmx284 19" 8 twist 4 groove..
Good luck with yours,
I'm eventually gonna get something chambered up in this-- Super LR
Love that longer neck for the VLD's.
1-8 twist in your .243 Win...? I was shooting a 30” 243 WSSM just under 2950 fps’…., I couldn't the DTAC 115gr. bullets too track straight at 1k... 600 yards it was still not where it needed too be. I was shooting the 1-8 twist... spoke to Tubbs... he thought 1-8 "might??", “should” “could” or “would”????’…, at that time; stabilize it with that kinda kick I had. It turned out I had to go to a 1.6.5 to get them where they needed to be. Not saying the accuracy was poor from a 1-8 twist, but I defiantly picked up quite a few more 10’s and X’s when I made the change. I just can’t help think a faster twist in a shorter barrel might help some what.
Maybe not; perhaps mine is an isolated case... but I would’ve thought a 30” barrel at 2950 fps plus in a 1-8 twist would have turned that 115gr fast enough.
well i guess i might have to go with 7.5.... i think thats what shilen offers.... 105 amax would be fine though...just need to kill prairie dogs....
