Back in early 2000’s, McCann Industries (known for their M1 Garand Gas Trap Adjuster) manufactured an M1 Garand in .458 Winchester Magnum. Not made anymore after the passing of McCann’s primary gunsmith, the rifles are a fine example of ingenuity and practicality applied to big-game hunting.

At first, I flinched just thinking about it, but the few videos of it shooting shed some light on how this big-game cartridge is tamed. While the base rifle was identical, McCann added an aggressive muzzle brake and a mercury cylinder to the stock to absorb and deflect the recoil.
