"when you're happy you enjoy the melody but, when you're broken you understand the lyrics".
Velocity based on barrel length is a linear relationship. Very predictable. This site is a good representation of velocity vs barrel length.

Basically, You are getting into 300 Blackout with a 10.5-12.5" barrel. Waaaaaaaaaaaay cheaper to build yourself a Blackout.
Mom's comin' 'round to put it back the way it ought to be.
Anyone that thinks war is good is ignorant. Anyone that thinks war isn't needed is stupid.
I think I've decided away from such a short barrel. I think I wouldn't mind a pistol build of around 12 to 13 barrel in .308, but I think I'm gonna head down the 300 Blackout road first. It seems like a better way to go and I know members on this very board have hunted elk with one.
