Thread: 1:7" twist 308 Who's running a ultra fast twist, super sonic and why ?

I have a 1-7” twist 308 improved case 18” barrel on a Remington goes extremely well with subs or supers
I run the 178 eld-x in it works extremely well but at high velocities it is a bit hard
On thin jacketed projectiles in the 95-130 varmint range they hold together
But are very explosive on impact

I run a 8.6 blackout with a 1-1” so is amazing how quick a twist you can make do with
At the speeds that cases around that size create it causes a spiral effect in the meat as it cuts its wound
Channel and can only run copper so expensive to run but very effective

But 1-7” or 1-8” at any speeds a 308 can pull can’t see there being much difference and
Both working well from experience or with customers experience playing with stuff they have
Had built
