Actually, I did read his post, about his shoulder issues. The 45-70 cartridge is very versatile and can be loaded very light, say oh, .357 magnum levels all the way up to stopping a cape buffalo.
I enjoy a rifle that can do everything, loaded up or down with a great deal of ability to maximize the load to the game/target in which it will be employed against.
I do love the .357 magnum, it might be my favorite pistol caliber, but as a long rifle, I feel like the 45-70 is more versatile, and versatility is something that I try to exploit.
