Why This Wins for Practical Shooters
Having run 1,200 rounds through my SPR build last month, Frontier’s consistency surprised me. The 55-grain FMJ maintains 2.1-2.3 MOA groups at 100 yards from my Spring TX CNC floor-built rifle – better than most bulk ammo at this price. The brass holds primer pockets tight through three reloads in my Dillon 750.

Frequently Asked Questions
Where can I buy Hornady Frontier ammo online?
F1Firearms (f1firearms.net) stocks multiple Frontier configurations with same-day shipping from Flagstaff, AZ.
Is this ammo reloadable?
Yes – the brass cases withstand multiple reloads when properly prepped. I’ve personally reloaded this brass 3-4 times without issues.
Will this cycle in my AR-15?
In 18 years of testing, I’ve never had a failure to cycle in any properly gassed AR chambered in .223 Remington.
What’s the muzzle velocity?
Hornady rates this at 3,240 fps from a 24″ barrel. My chrono showed 3,180 fps from a 16″ mid-length gas system.
Is this corrosive ammo?
No – Frontier uses modern non-corrosive primers and powders. Standard cleaning procedures apply.
Can I use this for hunting?
While possible, FMJ isn’t ideal for hunting. Consider our hunting ammunition with expanding projectiles.

Product quality is solid but the website could use some work. Hard to find what I was looking for at first. The Hornady Frontier Brass .223 Rem 55-Grain 150-Rounds FMJ -… itself? No complaints.

Been in the market for a while and finally decided to buy from F1firearms. I was comparing this against similar products from eBay and decided to take the chance. Glad I did. Arrived in 3 days, well-packaged, and the quality speaks for itself. Installed it on my G19 Gen3 and ran 384 rounds through it without a single hiccup. This is the real deal.
