Looking at the '.223 /.308 aren't dead' thread had me playing around with numbers on my ballistic app.
Now I'm wondering how fast a fast twist .308 20-22 inch barrel could push a 225gr Eldm? Assuming AI mag length constraints of approx 2.86 oal.
Even very modest velocities (2300-2500fps) produce fairly stunning ballistics
Anyone here messed with the heavies (not including Warner Tool stuff) from a .308
Would an 8 twist barrel be overdoing it?
