Anyone who would say the .45/70 is 'better' than a .458 WM or any other of the more powerful rounds is being a mite silly.
; My problem is with people who look at 405gr. bullets at 1,320fps or 500gr. bullets at 1,210fps, who judge the round by those black powder ballistics and will not look at what the round has become in modern guise. It is difficult, I suppose, for people with little or no experience with these rounds, to access them in thier 'new' light.
: reflex264 - thankyou for showing us the work you've done - excellent - it's a lot of work to test as you've done. I am really amazed as the good showing of the light for calibre 300gr. Nosler. I had never considered it a viable weight in .458 calibre.
: The bullets that really have me interested, is full power loadings in both .45/70 and .450 Marlin with the 350gr. "X" and newer 350gr. TSX bullets as well as the 350gr. Speer FN. I think, if driven to 2,100fps or a bit more, they'd make a good show. This may be too low a velocity for the "X" bullets to expand past calibre, though.
: The Lyman cast bullet #462560, a flat nose design with large meplat weighs 560gr. in WW metal from my mould and should also put in a good showing. I was able to drive it to 1,850fps in the .458 2" using H4198 and could have added another 100fps with slower powders, I think. It's nose is too long for the lever guns, unfortunately.
