While I have never shot the .458, I find it alluring as a big-bore cartridge. Quickly gaining a following within the MSR market, the cartridge balances a wide range of capabilities and bullet weights to create a versatile package.Unfortunately, this growth in popularity has stretched its manufacturing base, with many loadings and parts difficult to find.

This makes GY6’s video either a treat or a horror, depending on your desire to shoot the ammo. Andrew goes full-auto with the big-bore and enjoys it. Slotted for destruction include pumpkins, meat, and includes a ballistics gel hit.
