You can get snap caps, and those little plastic gyprock screw inserts work , but I just pull the trigger on a empty chamber most of the times.
The proper snap caps don't last very long.
If you are anal, you can use a fired case, I don't like the idea.
I had a couple target rapid fire guns that I would do that , but the firing pin would hit the barrel on them.
At one time I had a lot of test 22 ammo, it was dummy rounds for testing 22 actions and they worked good, dark green in color , but I have used them all up .
Forgot where I got them 30-40 yrs ago.
International Firearms maybe?
