This has nothing to do with the OP but I knew a man, gone now unfortunately, who had only one shotgun, one gun for that matter. It was an ancient 870. He had a couple of different barrels with it. The one it wore around the house was a handsawn 18" barrel (he said 18, who am I to argue
). This guy hunted everything from woodcock to moose with that old gun, no telling how many tons of shot had gone thru it. Some folks like to have lots of guns around, some make due with just one. Gotta tell you, a few of those old guys with just one are pretty danged scary.
