    457WWM is the Wild West Mag. It's the same as 45-70 plus 0.100" OAL. GS Custom bullets is a company that makes bullets. Solid copper drive band FN. Reloader 7 and H322. Click the Gunblast link as well. I had 24 Marlin XLR, Paco had a ported 18.5" guide gun.

    Most powerful lever action cartridge

    Some of the common discoveries were as you would expect. For instance, since bolt thrust (maximum) is a constant, increasing the cartridge diameter yielded no net gain of energy. The higher pressure and faster powders in the 45-70 created more efficiency and negated the gain of larger case...

    Not enough penetration indeed, especially on hard bone...it would be near or at zero in some cases. But not as powerful as either of the top 3 contenders. My personal 45-70/457WWM loads have touched 5000 lb/ft.

Over many, many penetration tests and tissue destruction tests, and medium speed, heavy 458 has proven champion. That very same load set the...

    Amen. Vince Lupo took the Dangerous 6 with one shot from a Marlin 45-70 guide (I believe) with lead cast bullets. Randy Garrett factory 540 Hammer heads at 1550fps.

    True, you can get ammunition, but not the rifles. Black powder does limit the cartridge, at least by pressure, to less then the 45-70 performance (both energy and penetration). That being said, the 50 Alaskan takes the lead. With handloading, the 45-70 still wins. If you custom build your rifle...
