AyersTG:

I don't know if you are aware of it, but a lot of .22 caliber rifles and pistols have a "shouldered" firing pin so that the firing pin cannot accidentally peen the barrel chamber rim.

My cheap little 14 year old Jennings J22 has that feature and it is one of the cheapest built guns made. I lucked out despite its reputation and ended up with one that never jams if kept clean (Good for about 60+ rounds before cleaning.) , which prompted me to buy 2 more magazines for it, all of which work flawlesly. I still wouldn't dry fire it because the slide that contains the hardened steel firing pin is made of soft zinc and eventually dry firing would cause an indentation on the firing pin stop and allow the firing pin to peen the barrel chamber.

I'll bet your Rossi has a shouldered firing pin. Check into it.
