I just inherited a number of guns and the most interesting to me are a .351 hunting rifle my great grandfather used for deer and moose, and a 45-70 that my grandfather says was manufactured in the late 1800's. Now, what I'm curious to know is didn't they stop making .351 in the 80's? Is anyone making it? The gun CAN be a permanent safe queen, but what fun is that? Maybe someone has brass and an idea for a safe bullet to load in it? The other thing is the 45-70. Being that it's around 115 years old it was obviously designed for a black powder cartridge am I right? Is there a smokeless load that's safe to use with it? Like a factory load? Any input would be appreciated. Thanks.
