Also round nose 110 grain carbine would be excellent with a fast burning powder (plinking). You'll still have a mad fireball but at least they will be stable and your effective range increases. Pulling it out of my ass here but I bet 110 vmax would stay supersonic to at least 700/750. Which if you can do that with an AR10 pistol..you dah boss. Heavy bullets are going to make it an expensive 300 blackout (and less-stable/inaccurate)...but light bullets properly loaded would be a fun niche.
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.
