Hello everyone, I'm new to this forum. I'm getting a Buffalo Classic .45/70 in a couple weeks and I wanted to load blackpowder cartridges for it. But now I've heard that the H & R barrels have micro-groove type rifling, if I understand correctly. So does this mean the Buffalo Classics are not well suited for blackpowder cartridges? Are there any special tips for shooting blackpowder in these rifles? I handload blackpowder cartridges for my .45 Colt New Vaquero, so I'm not totally new to this.
