This happened a couple of months ago. My firing pin broke on this .45 Colt rifle. Henry replaced the pin free of charge. I have now broken it again. I am sure this time they will ask if I was firing reloads. Of course I was. I put a couple of thousand rounds-all cast bullet reloads-through it the first time. This time less then 500. I am using the Lyman cast bullet manual. Mid range, with Trail boss powder. Winchester primers. Anyone else with issues on lever action pistol caliber rifles? Wanna kill these ads? We can help!
