To not totally derail the beautiful #1 Ruger in the classifieds I thought to continue the discussion of this Monster Rifle cartridge. New powders introduced and are capable of pushing this cartridge into near anti tank rounds. LOL New loads achieve 2600 fps with 2.5 tons of muzzle energy, prior to the introduction of new powders the round was rated to be used inside of 110 yards, 2150 fps and the 2.5 tons of muzzle energy. The new loads stretch it out to 500 yds still carrying a measly 1 ton of energy. LOL. I've only seen, up close, 2 rifles chambered in 458. The first was used in Africa and resided in a high earner lawyer's safe. Model 70 Winchester. The second one was sold by the Arkansa Game and Fish, they had used it for alligator eradication in southern Arkansas. I didn't see a third one a fellow was sighting in but felt the concussion 3 lanes down at a local indoor range, it was so loud and the concussion made it impossible for me to use the lane I was in and had to move 2 lanes further away. Sucker would cause a big flinch when he fired it. LOL Had he offered a couple of shot free use I would have passed, thing has 70 ft pounds of recoil. Unless you have a beefy shoulder I advise staying away from the big belted magnums, they can hurt you. When I was much younger I wanted a 375 H&H rimless nitro express double rifle, they were out of my purchasing ability and still are.
