I'm thinking of putting together a 300 Blackout SBR upper, 6"-8.5" barrel length, for 100% subsonic suppressed use with 190-220 grain projectiles.
I was fairly settled on a particular barrel that happens to have a 1/8 twist, but recently I saw another Faxon is offering 1/5 twist barrels.
I'm wondering if the 1/5 would stabilize the subs better than the 1/8?
Anyone running subs in 1/8 or 1/5 care to share your results?
