22 is a good suggestion but be carefull. I've lost 2 nice 22's to the wife that way. I've got to go buy a 3rd just for me to shoot and now my daughter is thinking about shooting. Maybe I should 2 more just in case?
I had the same problem with my friends. That is why I have 3 of them now so we cann all shoot at the same time without having to trade back and forth.
