Do they last? I have purchased many 22 snap caps that have only lasted one or two firings. Most no more than one.

I assume you slip a bit of thin plastic in front of the boltface and pull the trigger. Should work on some guns.You lost me with that one?

I've always stored auto pistols in half ####. {no compression on the firing pin spring} Have I been storing incorrectly all these years?
There are still a few rimfires made that are not safe to dry fire. I bought a little Henry singleshot for my kids, and the firing pin will hit the edge of the chamber on that one. I just use a spent case if someone wants to dryfire it.

Compression does NOT weaken a spring, cycling it does. As for dry fire, its a non issue even with rimfire. If you think the firing pin is going to peen your breach face the your firearm is a piece of sh*t. I've never not dry fired the life out of all my rimfire guns and never had an issue.

The answer here is #4 drywall anchors for sure. They fit the chamber perfectly and last through a lot of dry firing. Also the cheapest you are going to get.
The metal ones (blue A-Zoom linked in the first post) are ‘action proving’ dummy rounds, which means you put them in your lever gun and crank the lever, or your bolt gun and cycle the bolt, or your pump gun and pump it, to show that the feeding system, magazine, extractor, and so on all work. Problem is, the rim is used for extraction, as well as being struck to ignite the priming compound. Pulling the trigger on them leaves permanent marks, and too many of these can chew up the rim and make them less functional for their intended purpose.
Apart from using spent casings, bits of plastic, and yes the small drywall anchors, they do make softer polymer snap caps for dry firing (usually found in clear red). The firing pin also makes permanent indents on the rim, but the material flows back a little, and as you insert them again the hits distribute randomly around the circumference. Generally they're good for a dozen shots or so. They're not as rigid and durable as the metal ones, which makes them a little less suited to cycling than the above type. Tipton come about ten to a package, which makes them like a buck apiece for disposable junk. I found a different brand in a local gun shop, they're only as long as .22 Shorts, but there's like fifty of the little red suckers in a pack for maybe six bucks.
Sorry, no firing pin should be causing any damage to the chamber on a quality built firearm.
There are some currently built Anschütz target actions, just for example, that you should not dry fire without a dummy or spent case in the chamber. Unless you take them down and insert a fake dry fire firing pin. We're talking like $4.000+ Olympic target rifles.
(My Izhmash Biathlon, on the other hand, dis-connects the firing pin when a magazine is not inserted.)
Its not about the pin breaking. Its about the pin peening the chamber. Most modern rimfires are safe to dry fire.
I'm not overly versed with high end biathlon rifles, but I still call BS. Any gun that can't be dry fired is junk and is far too finicky to be practical.
