Description
There's a reason Buffalo Bore calls their lineup "Strictly Business," and this 458 SOCOM load is a good example of why. This isn't a plinking round or a light-recoil range load. It's built for hunters who need a cartridge that will drive deep through a 2,000 pound animal without the bullet coming apart halfway there.
What Makes This 458 SOCOM 350gr Load Different
The 350 grain semi-jacketed flat point bullet in this load is built stiff on purpose. Buffalo Bore keeps the muzzle velocity around 1710 fps out of a 16 inch barrel, which is slower than what you'd see from a 458 Win Mag, but that's the point. At that velocity the bullet doesn't mushroom or fragment on big bones, it just keeps driving straight through. That translates to deep, reliable penetration on large, tough animals rather than a bullet that expands fast and stops short.
Buffalo Bore's Hunting and Sniping Philosophy
This load falls under Buffalo Bore's Hunting and Sniping line, which was put together specifically for people running AR-platform rifles chambered in 458 SOCOM who want options for everything from medium game to true dangerous game. The 350gr and heavier loads in this lineup are the ones built for the animals other cartridges can't handle cleanly, think bison, big bear, and other North American game that requires serious penetration rather than expansion.
Why Hunters Reach for the 350gr Semi Jacketed Flat Point
With right around 2270 ft-lbs of energy at the muzzle, this round hits hard while still being manageable in a modern sporting rifle platform. It's a load built by people who test their ammo on actual animals, not just ballistic gel, and that shows in how the bullet is tuned to survive impact with heavy bone structure. If you're hunting animals where a pass-through wound channel matters more than rapid expansion, this is the kind of load that gets built for exactly that job.

Frequently Asked Questions
What game is the Buffalo Bore 458 SOCOM 350gr load best suited for?
This load is built for large, tough North American game, the kind that weighs well over 2,000 pounds. Because the bullet is designed to hold together and penetrate rather than expand, it's a good choice when you need a reliable pass-through wound channel on heavy-boned animals like bison or big bear.
Will this ammo cycle reliably in an AR-platform 458 SOCOM rifle?
Yes, this load is built with AR-platform 458 SOCOM rifles in mind and functions well in that setup. Buffalo Bore designed the entire Hunting and Sniping line around the popularity of AR-based SOCOM builds, so cycling and function have been part of the development from the start.
How does the semi-jacketed flat point bullet perform on impact compared to other 458 SOCOM loads?
The 350 grain semi-jacketed flat point is loaded at a velocity low enough that it doesn't mushroom or fragment on impact with heavy bone. Instead of dumping energy fast like a hollow point, it stays intact and drives straight through, which is exactly what you want on the biggest game animals.
How does this 350gr load compare to Buffalo Bore's other 458 SOCOM options?
Buffalo Bore builds several 458 SOCOM loads with different bullet weights and velocities to cover everything from medium game to subsonic suppressed use. The 350gr semi-jacketed flat point sits in the category built specifically for the largest, toughest animals where deep penetration matters more than expansion.
