The Lyman 12213 precision shotgun snap cap is similar in weight to standard ammunition, ideal for realistic function testing. This is especially useful for releasing the tension on the mainspring for long-term storage of your shotgun. Cowboy shooters use shotshell snap caps for loading and dry fire practice.

Have only used the Azoom caps once, but you can tell from the feel that they are heavy duty. Not like the cheap plastic caps I had purchased previously. I wish I had seen these first!
