I keep hearing people concerned about "over penetration". Use proper tactics and this mitigates the risk. The other risk is the stray pellet, Shotgun pellets have a way of acting unpredictably. A Shotgun lost favor with me as a general purpose gun years ago. Today, for me its only use is defending a position and I generally want slugs, but 00 buck will do if they are close enough.
My rifle and pistol are tools, I am the weapon.
