Look at the regs, you can hunt with a centerfire pistol with a case {unloaded} of 1.5" or larger {pretty sure thats the length} and it has to be at least a .243 or larger. I hunt with .243 pistol, and have with others. Of course NOTHING beats a bow. If you read the regs on squirrel hunting you can hunt with ANY ammo, and yes this does include centerfire rounds. Hope this helps..........SKI
