as i see it, if your lucky as a youngin you start out with a 22 cal. then graduate to higher cals. as you get older. if your real lucky you get to hang out at the 41 - 45 cals awhile until your eyesight and your hands decide they would like to go back to the 9s and 22s awhile. so in my case i think they are all my favorite. my motto IF IT FEELS GOOD SHOOT IT.
