Yeah, the fact that the 45-70 pushes the same weight bullets as fast as the .500 does at lower presssures is a real bummer. What a schitty round!
So is the fact that the .45 slugs penetrate better since they have better sectional densities..And finally, the 45-70 is a real poor choice because you can get it in an realaively inexpensive factory lever rifle like the Marlin and brass ,bullets and load data a easy to come by..
I'm sure 400 grain 45-70 slugs freaking BOUNCE OFF Bull moose and Bears..
