[And, I bet you're scavenging other people's brass. Admit it.
Well, jee whiz... If those guys aren't reloaders... I sweep and can't help it if some other odds 'n ends are mixed in there... I can't be kneeling down sorting through EVERYTHING in the moment... and, besides, some of my guns hurl MY brass all over the place which I can't recover... soo... I'm due some to make up for those far flyers.
But anyhow... That IS, in fact, part of the reason I finally got into .40... 'Cause I accumulated a bunch of those mixed in... and just couldn't figure out what to do with 'em... 'Cept buy a gun and set of dies to fit 'em... It's only logical!
Now I'm trying to actively ignore those .357 Sigs I've accumulated the same way... (And also looking to see what guns might best fill that need... JUST IN CASE I win the lottery or somethin'... heh heh...)
