Little fingers are for more than M-16's, but a very important point. The actions on some guns can "hide" a round that can later "turn up." When I got out of the army, I was very weapons aware, you could say, and went through the family arsenal, checking everything out. We had an old pump 22 short that evryone for 3 geberations had learned to shoot with. Well, it was tired, needed a complete over haul, including a new barrel, so I went ahead and had the barrel replaced, and the action modified to shoot long rifle ammo. I told my Dad, and my brother about these changes, but they never seemed to fully get the fact that the old gal shot LR's now. Over the next 20+ years, the old gun would come out ocassionaly at family gatherings, and there were a couple of incidents where there were FTF-FTC issues, and at each of these times I reitterated that the gun had LONG AGO been changed to a LR chambering. Then about 25+ years ago, here the 2 of them are sitting on my Dad's deck on a lovely Georgia day-fiddling around with the old rifle, yet again, pumping it and looking in it while feeding yet another load of 22 shorts into it. OH MY! It wouldn't fire! Or would it? There are women and kids and dogs milling all around all over the deck and... CRACK! right when these two experts weren't expecting it. One of the shorts jostled loose and finally chambered. Now, in my family, having a gun you are holding go off when you didn't intend it to is serious business. They both looked like they had soiled themselves. I told them one last time that it didn't shoot 22 shorts, just long rifles. Fortunately, there was no harm done by that round. I took the rifle with me when I left. Their assessment was the I had broken the old pump-oh well. It took me some doing to get all of the ground up brass out of the action, but it shoots great-22 long rifles that is. Flapjack.
