Re: Reliability of .50-70 models

I have shot several '66s (in good condition) without any issues. I just finished restoring a '66 Short Rifle with an almost new bore. Its first trip to the range was last weekend and it worked well. The block pivot bolt should be loose. That allows the block to float so all the firing load is taken by the cam, not the soldered hinge strap. Theoretically, you can leave out the pivot bolt and it will lock up fine. The only 50-70 Trapdoor that gave me trouble was an M-1870, which had rather generous headspace. It tended to stretch cases and quickly found a home in a museum.
