Ballistics typed on paper is not what always happens in hunting conditions.
What do you think would put an elk down quicker at 100 yards...........
A 220 Swift with with a 55 grain bullet or a 410 grain from a 45-70?
220 Swift energy is 1,004 by the book.
45-70 energy is 895.
I have yet to see a grizzly guide use a 220 Swift, but many carry a 45-70. Yeah I know newer guns can handle potent 45-70 loads, but I have used factory Remington ammo (to old load pressures) in my original 1873 trapdoor to take several elk.
“Book energy” by no means indicates penetration capability. But, you already knew that.
