I am shooting a M1886 .45-70 Springfield trapdoor, mostly with BP. However i ran a few rounds through it with Reloader 10x (35gn) and a lead cast bullet (405gn), No crimp, lubed. I want to keep using smokeless.. BP is just getting to be a hassle.
Now, all the manuals tell me everything should be fine. The cartridge, and primer looked ok after shooting. There was some of burned powder residue on the outside of the cartridge after firing. (more than usual on a fired cartridge) I believe that mean it may be under pressured.? not sure.
My concern is, how the hell am I to know if i am putting too much PSI on this gun? I love to shoot it, but i don't want to do so while slowly degrading the gun over time.
Anyone else use Reloader 10x in the trapdoors?. I just want to keep the pressure under 19000.
