To protect the rifle and chamber, I bought (supposedly "soft") steel snap caps off Amazon. They destroyed the firing pin.
FORUM BOSS: Rimfire firing pin contacts the RIM -- NOT the center of the cartridge. Those snap-caps are NOT designed for rimfires!!!!
The Amazon .22 LR snapcap is made from ALUMINUM. But even that may not be ideal.
