Just bought a Marlin 1895G in 45/70 I reload my own cartridges for my other guns, and want a good load for this gun. I have seen factory ammo offered by a company called Buffalo Bore boasting energy levels of 3500 ft. lbs. with a 405grn bullet. Would like to make my ammo as powerful as possible and duplicate these numbers. What is the difference in say Winchester factory ammo and this Buffalo Bore? Better yet does anyone have any load info for this caliber that I could try? Thank you much for any input.........Charliebuck
