A surprising number of centerfire ctgs. will FIRE in a .410. I have to admit to firing some of them back when I was young and immortal
But the only sensible use for this knowledge is to remember that when you only have a .410--but no .410 shells-- and ABSOLUTELY HAVE to kill something up close and personal, you can if you know what else will chamber and fire. The .410 may never be the same, but you'll be alive.
