Question for reloaders [View all]

I live in snake heaven. Every year I wind up shooting at least 2 or 3 rattlesnakes on my driveway where they crawl at night to sleep on the warm asphalt. I've used a single shot .410 loaded with 00 buck (home defense loads) to dispatch the critters but I don't think I need this much firepower. And I'd rather use a handgun. My question is this.

I have tons of .45 Long Colt brass and several revolvers chambered in .45 LC. What I want to do is load them with powder, cardboard or styrofoam for over powder cards, some 7-1/2 bird shot and a cardboard over shot card (no crimp) sealed with some white glue. Or do the same thing in cut down .410 hulls to be fired from the .45 LC revolvers.

Anybody have experience doing something like this?
