RE: Need new gun to replace 270 "help"
99 percent of the factory loads for the 45-70 now adays are smokless powder. I think only the cowboy action loads are black powder and may of those are not either. Garret and Corbon make loads for the modern 45-70 that will take any animal on earth. If you don't reload and still want the thump of the 45-70, go with the 444 Marlin or the 450 Marlin.
