There's nothing wrong with the 405gr Remington (traditional version). It's tougher than the 350 Hornady and as tough as the 350 Speer with 55 grains more weight. It will leave the barrel of my Marlin Classic with a 22" barrel at over 2000 fps with a couple of powders. Also, a good heavy hardcast can't be beat. 465 grainers at 1900 fps will flatten anything on this contenant and in most other places as well.

My pet 45-70 is my Ruger No.1 long-throated that will easily match a 458 Win Mag with equal barrel length. My go-to load is a 350gr TSX at 2400 fps. There are no flies on the 45-70 as a stopper.
And, I do own and shoot a CZ550 in 458 Win Mag.
