I have flaunted with the 45/70 on and off. Of late I have been playing with a 1874 Shiloh Sharps. A friend has convinced me to try his load of a 500gr paper patched bullet with 70grs FF in my hoarded nickel plated R-P cases. These are the best I have ever tried in this rifle. 5shot ragged hole at 100yds. I would not consider anything but Black gun powder in a trapdoor, no matter what anyone wants to tell you. And for a Black load, it is tough to beat a proper paper patch load. I have a line on a original 420gr Sharps mould and will be trying the Sharps company load of "45/75-420".......also a good load to try, of which I have used the 405 LEE bullet cast with wheel weights, is the Springfield Cadet load of "45/55-405". It is a sweet shooting load, in a light weight Trapdoor carbine they would be correct and fun to shoot.

In a Rguer or a marlin load it how ever you want, with whatever bullets. But in a Sharps or a Rollingblock or in your Trapdoors, a quality lead bullet with black powder is the way to go, in my humble opinion.
