Thinking 'bout maybe getting an NAA .22 mag revolver, little single action pocket gun. However years ago I helped sight in a friends new Marlin .22Mag rifle. Once sighted and after seeing how accurate it was, for fun we put a golf ball atop a 1x2in. post and tried to hit it at 100yrds. After several tries from the both of us the ball did not move. I exclaimed that the rifle was accurate and called the next shot to hit three inches below the ball. That shot made the post wobble like it was going to come out of the ground. Upon inspection downrange neither of us missed, several small holes on only one side of the golf ball which never moved. Is the .22Mag a decent choice for backup/deep deep concealment? Thanks.
