RE: Have you considered ............
"The 45-70 has slain man and beast in every field with a lil sissy 350-500 grn bullet soundering allong at a measly 1800fps"
Believe that the original military load was a 405 grain bullet and 70 grains of BP for about 1,400 fps. I do understand what you are saying here.For a few years i hunted with 130-150 grains of Pyrodex. Found out that such heavy loads arenotnecessary. I shoot onlya fewloads in myinlines. Do not really care what the velocity of those bullets are. They kill deer and hogs as if struck by a bolt from above and that is all that matters to me.
