After loading and shooting some full bore loads for the 45/70 I was looking at max loads for my 458 Socom. For the 405gr jacketed bullet, it was exactly the same as the max load for 45/70. 48gr of IMR3031 in either one. I think this almost = same velocity, except my guide gun is only 18" barrel. Recoil from 458 Socom is much less. Anyone else loading this caliber? Makes me want to get rid of 45/70 if I can get same ballistics from semiauto.
