Reloading .45-70 with 405 grain lead bullet over FFG. After doing all the other necessary stuff I belled the case mouth. The bullets fit in nicely by hand but when I went to test chamber my dummy round the breach block on my C Sharps 1875 required lots of force to open. The brass was WW full lengthed resized, trimmed to specs. I should add that a new unsized, un-belled piece of brass extracted just fine. So did I put too much of a bell on the cases and if so how to adjust the die to do it just right. I should add that this is first time reloading straight walled cases, I've reloaded bottlenecks before. Thanks.
