I was test firing my Martini Cadet that I had rebarrelled to 357 magnum. I shot some 38 specials and all was well, then I fired one sellier and bellot 357 Magnum and the action was stuck. I had to tap on the breachblock with a piece of wood to open it. I had read that sometimes the firing pin hole needs to be bushed but the firing pin doesn't seem to have much of a gap with the hole. Any ideas?
