Why anyone loads a 45-70 past the 1870's standard load with a 405 grain bullet at 1350 FPS is beyound me. There isn't an animal in North America that could stop one of those bullets at that speed...
Agree with this observation.
On the other hand, I do load a few 305 gr Lehigh Penetrators (brass solids) ~1700-1850fps with 43-44gr of RL-7, 40gr of 5744 or 43gr of H4198 when am feeling out toothed and clawed by illegal immigrant bears near the Canada/USA border.
With 420gr wfngc I like around 41-44gr RL-7...
