Your last sentences regarding the .45/70 - are you referring to a Trapdoor Springfield's loads, Model 86 or 71 Winchester or Marlin loads, or a Ruger #1 or bolt gun's loads? It does make a difference.
The bolt gun and Ruger can make 2,050fps with 500gr. solids.
What are the 'actual' chronographed ballistics of the .470? Granted the larger bullet of the .470 does or should have an effect - with equal bullet integrity, of coruse, but I think we might have a stalemate there on charging game.
It would only be a stalemate on paper I reckon. The .470NE with a 500 grainer at 2050fps would be running 40,000psi or less, and with the bullet seated to proper depth in the case neck.
How much pressure is a 45-70 running to achieve 2050fps with a 500 grainer, and how far out is the bullet seated in the case?
For DG, and more so for charging DG, give me the low pressure .470NE anyday.
