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?
