so i got a couple few aa snap caps for 12 ga (after my previous post about azoom snap caps deteriorating pretty quickly). very nice ebay seller, and handled a glitch on my end very graciously, BUT one of them seems to be a couple microns too big-- sticks in the chamber. anybody else tried aa snap caps? any luck? any bad luck? i like the look and feel of these, and the brass does wear, but not as badly as the azoom, but i'm still a little disgruntled. 12ga snap caps aren't cheap for what they are. again, no complaints with seller, just with one of 4 caps. ???
