45 acp burns its powder too quick to worry about that. After 10" of barrel the bullet starts to lose velocity from friction

Quoted:
Anyone experience supersonic factory 45 ammo through their rifle barrel? 185 grain probably, but any 230 or 200 grain? Some good info: http://www.ballisticsbytheinch.com/45auto.html |

I'm getting about 1080fps with 6 grains of either Unique or WW 231 and a 230Gr bullet out of my Kriss Vector CBR .45 carbine with a 16" barrel.
