The only guns I can see not shooting are valuable collector pieces. For guns that may be somewhat common, but have a large degree of emotional value, I'd shoot it like it was designed to be shot. Sure, there may be some memories attached to them, but there's also a chance at making many more! I used my grandfather's rifle(Marlin 336) to shoot my first deer @ 13. He passed on the year before i was born. I'm sure he'd rather the rifle be used than gather dust in the back corner of the safe, and while I didn't get a chance to know him, I like to think he would have been proud, and just may have been there with me that day, helping me make the shot. Regardless though, I have a hard time possessing guns and NOT shooting them. Luckily my tastes run more along the lines of practical than safe queen. But the older guns i do possess...the aforementioned marlin, his 62A Winchester, etc.....get shot. Not every day, but they are maintained in good working order and I'd be fine with shooting any of them at any time.
