Hornady Frontier .300 AAC Blackout 125gr FMJ — 500 Rounds

The Hornady Frontier 300 Blackout is the range and practice load in the .300 AAC Blackout category.

A 125-grain FMJ at 2,175 fps and 1,313 ft-lbs, loaded with Hornady bullets and military-grade brass and primers in Hornady’s value-tier Frontier line.

At $1.00 per round for 500 rounds, the Hornady Frontier 300 Blackout is the most affordable .300 BLK load in this category.

56% less per round than the Barnes VOR-TX TAC-TX at $1.875.

Frontier — Hornady’s Value-Tier Practice Line

Frontier Cartridge is Hornady’s dedicated practice and volume shooting line, distinct from the premium BLACK, ELD-X, or ELD-M lines. Three things position it:

Hornady bullets. The same bullet manufacturer as Hornady’s premium lines — not a rebranded commodity bullet. Hornady’s non-steel core FMJ bullets are confirmed acceptable at most indoor steel-core-restricted ranges.

Military-grade Boxer primers and brass. Reloadable, non-corrosive, with the quality control Hornady applies across all production lines. Consistent ignition through high-volume range sessions is not a given with value-tier ammunition; Frontier’s military-spec primers address that.

Affordable volume. At 500 rounds per case and $1.00 per round, the Hornady Frontier 300 Blackout is loaded specifically for the shooter who trains regularly and needs to confirm function, build trigger time, and develop fundamentals without the cost of hunting or defensive loads.

The .300 BLK Training Gap

The four hunting and defensive .300 BLK loads in this category run $1.56–$1.875 per round. At those prices, 200 rounds of function confirmation costs $312–$375. At $1.00/round, 200 rounds costs $200.

For shooters who carry suppressed subsonic or hunt with the other .300 BLK loads in this category, the Hornady Frontier 300 Blackout FMJ provides the volume practice opportunity at a practical price point.

Frequently Asked Questions

Is FMJ appropriate for steel-cased restricted indoor ranges? Yes — Hornady confirms Frontier uses non-steel core FMJ bullets, making it acceptable at most indoor ranges with steel core restrictions. Verify with your specific range before purchasing.

Why use FMJ for .300 BLK practice instead of the hunting or defensive loads? Cost. Frontier at $1.00/round vs $1.56–$1.875 for the hunting and defensive loads in this category. 200 rounds of function confirmation costs $200 with Frontier vs $312–$375 with the premium loads. The FMJ doesn’t replicate expansion or terminal performance, but it confirms function, feeding, ejection, and trigger fundamentals at a sustainable price.

What makes Frontier different from generic budget FMJ? Hornady bullets (same manufacturer as their premium BLACK and ELD lines), military-grade Boxer primers for consistent ignition, and brass cases for reloadability. Frontier is a volume line with Hornady quality control, not a repackaged commodity load.

Is this subsonic? No — 2,175 fps is well above the speed of sound (~1,125 fps). This is a supersonic load. For subsonic .300 BLK, see the Fort Scott TUI 190gr and Winchester Super-X 200gr in this category.

What does G1 BC 0.25 mean? Ballistic Coefficient 0.25 is moderate for .300 BLK. It means the bullet loses velocity relatively quickly at distance compared to higher-BC loads. For the range distances where FMJ practice shooting occurs (25–100 yards), BC has minimal practical effect.

Can I reload the brass? Yes — standard brass, Boxer-primed.

How many rounds is 500? 25 × 20-round boxes — the largest package in the .300 BLK category.

What’s the per-round cost? $500 / 500 = $1.00 per round.
