Not bad.... but wears out - A-Zoom Rimfire Action Proving Dummy Rounds

A decent product to help protect your rimfire.... but the firing pin dimpels the round and wears out after a couple shots. Better than a spent case by about 8 additional shots. Disposible.
Pros: Price, provides protection for rimfire firing pin
Cons: Dimples pretty deep, need to rotate after 10 shots
