Since I haven't posted this for many years...
I cut the plastic off of an old shotshell and punch out the primer. Fired .22 brass slides easily into a shotshell primer hole. You can check the dent on the .22 brass to see how the firing pin is doing. This should be fine for checking a hardware store gun. It's easy to carry and easy to check to see that the brass is inert.
