I am buying a H&R Buffalo classic with the 32" Barrel. This is my first 45-70, I reload for all my pistols and rifles everything from 9mm Luger to 300 Weatherby. My Question is in my reloading manuals they show 3 seperate listings. One for Trap Door, one for Marlin Lever Action and Ruger #1, Where does the H&R Buffalo classic fall? And would appreciate any Info.
