Black Powder Cartridge Rifle Question

[HawgHunter]

I just picked up a C. Sharps Arms 45-70 at an estate sale. It is a beautiful rifle but I have zero experience with black powder cartridges. Can you use BP substitute powder like Blackhorn 209?

I reload center fire rifle cartridges so I plan on loading my own. Any info will be helpful. :?:

Yes, I have seen data with some of the BP substitutes. You may have to look at some powder sites to see what they have, maybe start with Hodgdon for 777 & Pyrodex. I'm not sure how B209 fits in with the others, as far as compatibility in cartridges.

If it's an older gun & you are worried about pressure, you can also light load the 45-70 cartridge with modern smokeless powder. There are choices on the ammo shelf too. Just follow a directions for a load that id safe in your gun.
