I have Marlin 1895 that I bought new just before Christmas. It shoots my cast bullets like laser beams with the light loads I run through it. I ran some loads with IMR 4198 that get into the upper end of standard pressure loads that are the non Buffalo Bore Magnum Lever Gun loads. Recoil with the heavier loads are comprable to my 870 Rem 12 GA with buck shot. The light loads are a pleasure to shoot. The hotter ones are not severe. Though I will stick with the lighter ones as they are more fun to shoot 50 or more of.
If you do the .45-70 Gov't I would suggest reloading for it if you plan on shooting it much. If you cast then you can shoot a whole lot for verry little. The brass life if great, and loading is very flexible from light gallery loads, up to elephant stopping power if you do not fear detached retina, or a bruised shoulder.
