Answer to your first question is Nope...won't work...Answer to #2, I've shot over 100 times thru the same carrier and still haven't had a primer loosen up ... and its still as red as it ever was, just clean it with soap and waterand a tooth brush...So if your still worried "will H&R stop making them" buy your self a couple of extra bags...they'll last ya a couple of life times....MTNMAN
