So, I decided to sell my S&W 500, and in exchange for the ammo I supplied with it, I am now the owner of an HR 45-70 Gov. SB2 w/22" barrel. So, upon referencing some load data in Lyman 51st, I discovered 3 different sections. One for the Springfield 1873, one for the Winchester/Marlin and one for the Ruger no. 1 & 3. I was told by a friend who has reloaded for quite some time, to NOT use the Ruger loads because of the pressure only the Ruger can handle.
If you reload for 45-70 and own a handi-rifle, just point me in the right direction, pls & thx!
