Thread: 308 twist rate

Why 1 in 7"?
I used to own an old Rem 788 with a Douglas 1:8 twist years ago...and that would be the fastest twist I would go. It was great with subsonics but found that it was very fusy when working up high velocity handloads. It didn't take much to hit high pressures of blown primers and that's the problem. With the larger diameter and heavier .308 bullets where it takes more force to go to full rpm in a high velocity load, you can reach too great a pressure just too easily in a tight twist barrel (in my experience)
