Ok, I was always under the impression that the Winchester and Remington factory 45/70 (Remington uses a 405 gr jacketed bullet while Winchester uses a 300 gr jacketed bullet) were safe for Trapdoors. I've fired a few boxes of these through my "Bannerman" 1873 rifle with absolutely no problems. If I'm incorrect in this, please let me know!
There are other loads which are loaded extremely hot and are for modern lever action rifles that handle considerably higher pressures - I believe these are from Black Hills or some similar company.
