I'm trying to decide which BP cartridge to choose. Your opinions and biases would be greatly appreciated. I have been looking at the Swedish rolling M67 rolling block in 12.17. I'd like a rifle with a good bore that will group well and am willing to trim 50/70 brass for it. But, if the chamber is worn at then I'll have it enlarged to a 50/70. I want to shoot it. Either way, the round is close to a 50/70 or would become one. The other rolling block is an 8mm. If I want shoot an 8mm, I'll buy a Mauser. I'd look for a decent looking rifle and convert it to a 45/70. With either cartridge, if I can group well at 100, I'll try farther. I might even consider butchering the stock and installing vernier aperture sights. My impression is that they improve accuracy. My question is whether a 45/70 is superior to a 50/70 between 100-200 yards for accuracy? Would you choose 45cal vs 50cal and why. Would you use the standard military sights or upgrade? Thanks.
