The Buffalo Bore 458 SOCOM 300gr Barnes TTSX lead-free rifle ammunition brings serious stopping power to AR platform hunting and tactical applications. Built around the proven Barnes TTSX bullet—a monolithic copper projectile with a polymer tip—this round delivers deep penetration and consistent performance without lead, meeting the requirements of hunters in lead-free zones or those who prefer non-traditional bullets for environmental reasons. The 300-grain weight in 458 SOCOM generates substantial kinetic energy ideal for medium to large game and provides shooters confidence in hard-hitting, reliable performance downrange.
Buffalo Bore is known for precision-loaded ammunition that goes beyond factory standards, and this load reflects that philosophy. Each box contains 20 rounds of carefully assembled ammunition designed for both hunting and precision shooting applications. The combination of the heavy 300-grain Barnes TTSX and the 458 SOCOM cartridge creates a formidable hunting round that doesn't compromise on velocity or energy. Whether you're running a 458 SOCOM upper on an AR-15 or a dedicated 458 SOCOM rifle platform, this ammunition delivers the ballistic consistency hunters and shooters expect from a premium ammunition manufacturer.
If you handload or prefer loaded ammunition that pushes beyond standard specifications, Buffalo Bore's approach to ammunition development makes this an option worth considering. The lead-free construction means compatibility with hunting areas that have adopted non-lead ammunition mandates, and the Barnes TTSX design has earned a solid reputation for expansion and penetration in the field.
| Caliber | 458 SOCOM |
| Bullet Weight | 300 grains |
| Bullet Type | Barnes TTSX (lead-free monolithic copper with polymer tip) |
| Rounds Per Box | 20 |
| Manufacturer | Buffalo Bore Ammunition |
This ammunition is designed for rifles chambered in 458 SOCOM, including AR-15 uppers in that caliber and dedicated 458 SOCOM rifle platforms. Always verify your firearm's chamber before loading any ammunition.
Yes. The Barnes TTSX bullet is a monolithic copper projectile with no lead content, making it compliant with lead-free ammunition regulations in many states and hunting areas. Check your local hunting regulations to confirm applicability in your region.
The 300-grain weight for the 458 SOCOM is on the heavier side, which means slower velocity but substantial sectional density and momentum for deep penetration. This makes it well-suited for hunting medium to large game where retained energy and penetration matter more than flat trajectory.
Each box contains 20 loaded rounds of 458 SOCOM ammunition ready to fire.
