RRA barrels are advertised as 1:10 twist. E.R. Shaw advertises 1:14 as their standard twist for 9x19. What twist rates are you using with what bullet weight and how accurate is it? I plan to shoot mainly 147gr subsonic ammo. TIA.

My Colt is a 1:10m and it drives tacks with anything I feed it. The 147 grn is very accurate, even through a suppressor.

Common twist for most all SMG barrels is 1x10. I shoot 147's for years out of 10" Uzi (1x10) and AWC can, and a barrel cut from SS blank that is 8.5" long 1x10 with AWC. There is 1x9 blanks available also.

Pistols are typically 1x16.
