Description

The Frontier 223 Rem 55gr HP Match Case is a 500 round bulk case of .223 Remington loaded by Hornady under its Frontier Cartridge label. It is aimed at shooters who burn through a lot of ammunition and want a known bullet behind a brass, boxer primed case rather than mystery imported stock.
What is in the case
Frontier Cartridge is Hornady ammunition wearing a working-grade label. It is loaded at the Hornady plant in Grand Island, Nebraska, with Hornady bullets, brass cartridge cases and military-grade boxer primers and propellant. The Frontier 223 Rem 55gr HP Match Case packs 500 of those rounds, normally as 25 boxes of 20.
The bullet in the Frontier 223 Rem 55gr HP Match Case is the Hornady 55 grain HP Match bullet, a boat-tail hollow point designed for accuracy rather than expansion. The hollow point here is a manufacturing artefact of the match design, not a terminal feature, which is a distinction worth understanding before you choose this for anything other than paper and steel.
Specifications and load data
Hornady rates the Frontier 223 Rem 55gr HP Match Case at 3240 fps at the muzzle from a 24 inch test barrel. Expect meaningfully less from a 16 inch carbine, which is normal and not a defect. The brass cased boxer primed ammo in this case is fully reloadable, so the once-fired brass has real value if you load your own.

On accuracy, treat the Frontier 223 Rem 55gr HP Match Case as good practice ammunition rather than a benchrest load. The HP Match bullet is the same projectile Hornady sells to handloaders, so the component quality is genuinely there, but bulk loading tolerances are looser than a hand-weighed match round. Most shooters see honest two to three inch groups at 100 yards from a decent carbine, and better from a heavier barrel.
It is worth knowing where Frontier sits in the Hornady line. Hornady Custom and Hornady Black are loaded to tighter specifications and priced accordingly. Frontier exists to put a real Hornady bullet in front of a shooter who is buying by the case, which is exactly the trade the Frontier 223 Rem 55gr HP Match Case represents.
Cost per round is the honest reason to buy a 500 round bulk case rather than boxes. Check the maths against our twenty round listings before you commit, because case pricing is not always the better deal once a promotion is running on the small boxes.
Honest notes before you buy
The Frontier 223 Rem 55gr HP Match Case is .223 Remington, not 5.56 NATO. A .223 round is safe in a 5.56 chamber, so most AR-15s will shoot it happily. The reverse is not true. If your rifle is marked .223 Wylde or 5.56, you are fine; if it is a tight .223 match chamber, you are also fine. Just do not assume the two are interchangeable in the other direction.
Match hollow points are not hunting bullets. The 223 Remington range ammunition in this case is built to group well, and terminal performance on game is inconsistent by design. Several states also prohibit hollow points for hunting outright. For varmints or deer-legal calibres, choose a purpose-built expanding load instead.
A 500 round bulk case is heavy and takes real shelf space. Store it somewhere dry and temperature-stable rather than a damp garage or a hot car boot, because primers and powder both degrade faster with heat and humidity cycling. Ammunition kept properly lasts decades.
Check your state and local rules before ordering. Some jurisdictions restrict bulk ammunition purchases, require a licence or permit to receive ammunition, or ban direct-to-consumer ammunition shipment entirely. We cannot ship where the law does not allow it.
The Frontier 223 Rem 55gr HP Match Case suits high-volume AR-15 practice, club competition and training classes where cost per round matters more than terminal performance. MAG5 Firearms is a family-owned FFL in Collegeville, Pennsylvania.
