Looks like a hand gun cartridge trying to compete with a 30-30. I would put this in the same category as the 500 S&W and the 480 Ruger. It's really cool and it'd be fun at the range.
Pros: lots of power, biggest boom at the handgun range, lethal to tactical turtles in lvl 4 armor
Cons: shortened lifespan of firearm, expense of ammo (reloading would ease this), heavy recoil, rifle ranges with handgun accuracy
Would I want this as a carry cartridge? Not a chance. I'll stick with .357mag or .45ACP. Would I want to have one? ABSOLUTELY!
