Just FYI, DON'T "dry fire" Savage breakopen single shots of any variety; the firing pins break easily if you do, and many used ones have broken pins. Replacement pins are fairly easy to find but a pain to replace, especially the ones held in with a crosspin.
If you get a 220, 219, or a Stevens 94, buy a snap cap for it. Much cheaper than replacing the firing pin. (DON'T ask me how I learned this.....)
