300 Blackout Twist Rate Chart

300 Blackout Twist Rate Chart - I was under the impression that 1/8 twist would be better for super shooting, like for. It also likes the 240 cast traditional lube bullets in my opinion a faster twist. The 240gr smks were keyholing out of my 1:8 twist faxon barrel but the 220gr smks are fine. However it does the 208 amax just fine. The 1/10 twist has problems over 200gr with some bullets. It seems that everyone still recommends the 1/7 twist for a 9 barrel length, for 300 blackout. It is about stabilizing different weight projectiles. Twist rate isn't going to have much to do with how it chambers or feeds. And i would argue for practical purposes the difference. A 1:8 will be fine for everything but 240gr and heavier.
