10,11 and 12" here. Reserve RPM opens doors,lack of same closes 'em.
Hint...................
Have you ever seen 10 twist be a hindrance to accuracy with the 150-155s? Or, same question with the 8 twist and 120-140s in 7-08?
I have never seen a quick twisted rifle shoot poorly with lighter bullets myself. I can’t see any negative to running fast twist with any well built bullet.
Next 300 will be an 8 twist just to get in on the heavier longer bullets that keep popping up.
I’d fast twist slows bullets and raises pressures in any meaningful way I cannot see it with my Magnetospeed.
