Hello Oscar,

The 458 Winchester Magnum is as the others have said it is, relatively inexpensive to shoot. The excellent Hornady 500 gr soft and solid bullets are not too expensive, and are excellent dangerous-game bullets. On the other hand, cast bullets intended for the 45-70 work perfectly in the 458 WM, and for the price of a mold you can have an unlimited supply. I like the RCBS 405 gr mold. It is a gas-check design, but the bullets work just fine without the gas check. Then there are the excellent 300 and 405 gr Remington bulk bullets, which are available at reasonable cost here in the States. I don’t know what the overseas situation is.

My favorite practice load uses military surplus IMR-4895 powder, which I realize you probably can’t get. But, there are many good powders for this cartridge. IMR-3031 is a very good powder for the 458 WM.

Good luck with your big-bore rifle. I certainly enjoy mine.

Take care, Tom
