No I am referring to the fact that 1000'S of buffalo died to the 45/70 when it was a black powder round.Modern power or smokeless powder made it even better.I load 350 grain hornaday bullets with 54 grains of varget @ about 1950fps that is just anawesome round for bear,hogs and whitetail.I would go with 405 grain on buffalo or just buy some rounds for that purpose.
