The HSM Bear Load .458 SOCOM 350gr represents a thoughtful approach to modern big-bore hunting ammunition. HSM matched this specific load to what the cartridge needed: heavy projectiles paired with temperature-stable powders and quality primers in brass cases you can reload. The 350-grain Speer jacketed flat point bullet exits at 1,700 feet per second with 2,246 foot-pounds of muzzle energy. That combination of mass and energy works particularly well on large game because the flat point design resists deformation at impact, allowing deep, straight-line penetration through thick hide and bone.
The .458 SOCOM itself was engineered around close-to-medium-range stopping power. It fires 0.458-inch diameter bullets in grain weights ranging from 250 to 600, with most factory loads clustering in the 300 to 350-grain sweet spot for hunting. HSM's Bear Load line dates back to 2011 and focuses on ammunition purpose-built for hunting scenarios where reliability and proven performance matter most. This 350-grain loading balances recoil management with the kind of terminal authority that hunters rely on when pursuing elk, moose, bear, and other large game at practical distances from AR platforms.
Each round includes a Boxer primer and quality brass cases that shooters can reload. HSM specifically selected powders that remain consistent across temperature variations, which matters if your hunting season spans temperature swings or different elevations. Twenty rounds ship per box, giving you enough to verify your rifle's zero and put rounds downrange for hunting.
This cartridge delivers ballistics comparable to the legendary .45-70, but inside a modern AR receiver with manageable recoil and the handling characteristics modern shooters expect. Industry standard 1-14 twist barrels shoot heavier bullets like this 350-grain load accurately without issue. The round thrives at ranges where AR hunters typically operate—inside 300 yards where its powerful energy advantage shows itself most decisively.
This load is designed for hunting large game including bear, elk, moose, and hogs, particularly with AR-15 platform rifles. The 350-grain flat point bullet delivers exceptional penetration on thick-bodied animals at close to medium hunting ranges. The full-power load generates enough energy to humanely take even the largest North American game.
Yes. The .458 SOCOM was engineered specifically to work in AR receivers and delivers ballistics comparable to the .45-70 in a modern platform you can shoot accurately from standing or supported positions. Industry-standard 1-14 twist barrels handle 350-grain bullets exceptionally well, making this a practical choice for hunters who prefer AR ergonomics and controls.
Yes. The brass cases come with Boxer primers and are designed to be reloadable. Standard large rifle reloading dies work with the .458 SOCOM. Load data for 350-grain bullets is available from major powder manufacturers for anyone wanting to reload their own ammunition.
HSM's 1,700 fps velocity with a 350-grain flat point sits in the middle of the performance spectrum for this cartridge, which ranges from subsonic loads around 1,050 fps up to faster hunting loads pushing 1,900 fps with lighter bullets. At this velocity, the flat point resists deformation and penetrates deeply rather than expanding, making it ideal for large, tough game.
