723189000561 Snap caps are great for dry fire practice because they let you concentrate on keeping the firearm steady during the trigger pull, which helps eliminate flinch when using live ammo. Solid aluminum Rimfire snap caps protect the breech face and will last for hundreds of "shots".BOO! 20/02/2015
I am a a gunsmith. I don't want holes in my walls (or me) when I work on 22's. I bought these SPECIFICALLY for action proving, feeding, dry fire. The FIRST time I used them was great, cycled through the feeding tube, ejected (yay, I fixed it). The SECOND time, no go. (Here is where you learn from my experience). Feeding issues. They "disappeared". They were stuck in the feeding tube and the spring wouldn't push them past the little bump inside. Oh, old, weak spring, stretched it little, nope. Well, this guy never cleaned his gun, maybe it is gunked up, disassembled the entire feeding mechanism, cleaned, lightly buffed appropriate areas, nope. They are getting stuck near the elbow of the feeding tube. Checked the set screw to be sure it wasn't protruding, nope. Is the elbow bent or damaged, nope... couple hours after starting this quest I discovered that the dummy rounds rims were deformed just enough (from the dry fire that they were bought for) that they no longer would go through the elbow... tried several new live rounds and viola, they flew through like the had somewhere to be... GRR!

Since you can't spring-load a rimfire snap cap, these work just fine. Yes, the firing pin leaves a dent, turn the cap a bit and try again until the rim is fully dented. I believe it is still effective even though the rim of the cap is fully dented. The point is to prevent denting the barrel edge and these do that just fine.
Of course, you can also use a fired .22 case for the same effect. It's just harder to chamber.
