Product Overview
Hornady Frontier is a budget line loaded to Hornady's specifications by Lake City, which gives shooters military-spec reliability at a civilian price point. The 125gr FMJ at 2,175 fps is one of the fastest supersonic .300 Blackout loads available. That velocity translates to 1,313 ft-lbs of muzzle energy, flat trajectory out to 200 yards, and reliable cycling in gas-operated ARs regardless of barrel length.
The 125gr bullet weight is a natural sweet spot for .300 Blackout range work. It is light enough to keep recoil mild but heavy enough to maintain decent downrange energy. Shooters running suppressed SBRs will find this load stays comfortably supersonic even from shorter barrels, which eliminates the accuracy problems that can occur when bullets go transonic in flight. For unsuppressed training, the lighter bullet also reduces the concussive blast that heavier .300 BLK loads can produce.
Frontier brass is Boxer-primed and reloadable, though the Lake City headstamp sometimes has thicker case walls that require attention during reloading. For volume shooters who want Hornady-quality components without the Hornady Custom price tag, this load makes a practical everyday training round. It pairs well with any standard AR-15 lower and .300 Blackout upper, needing only the caliber-specific barrel and no magazine or bolt changes from 5.56.
- 2,175 fps muzzle velocity is among the fastest supersonic .300 Blackout loads, producing flat trajectory to 200 yards
- Lake City production means military-spec reliability at a lower price than Hornady's Custom line
- 125gr bullet keeps recoil light and stays supersonic even from 9-inch SBR barrels
- Brass is Boxer-primed and reloadable for handloaders who want to save on .300 BLK components
- Lake City brass tends to have thicker case walls, requiring extra attention when reloading to avoid pressure issues
- 0.27 G1 ballistic coefficient is on the lower end, losing energy faster past 150 yards than heavier bullets
- 125gr FMJ has limited terminal effect on game, restricting this load to range and training use only
- Frontier line occasionally shows wider velocity spreads than Hornady's premium offerings
