Frontier 223 Rem 55gr FMJ by Hornady – Reliable 20 Round Box

Description

The Frontier 223 Rem 55gr FMJ load, item FR100, is a 20 round box of 223 Remington ammunition from Frontier Cartridge, a brand made by Hornady. It pairs a 55 grain full metal jacket bullet with new, reloadable brass and is rated at 3,240 fps.

Frontier 223 Rem 55gr FMJ Overview

Frontier Cartridge was originally created as a partnership tied to Lake City production and today is a Hornady brand focused on affordable, high-quality practice ammunition. The FR100 is its basic 223 Remington load, built to the same quality standards as Hornady’s other lines but priced for volume shooting. A 55 grain full metal jacket bullet is the classic training choice for AR-15s and bolt-action 223 rifles. The new brass cases are boxer primed and reloadable, so handloaders can save their empties for later use.

Intended Use

This is range and training ammunition. Full metal jacket bullets do not expand, so they are a poor choice for hunting or home defense, where they can over-penetrate. Use this load for zeroing, drills, plinking and function testing, and choose a dedicated hunting or defensive load when it matters.

Bullet and Ballistics

A 55 grain bullet at about 3,240 fps from a test barrel shoots flat out to typical carbine distances and suits 50 or 100 yard zeros. Expect lower velocity from short barrels such as 10.5 or 11.5 inch pistols and SBRs. Light 55 grain bullets stabilize in almost any 223 or 5.56 barrel, from older 1:12 rifles to modern 1:7 barrels.

Firearm Compatibility

Fire this ammunition in firearms chambered for 223 Remington. Rifles chambered for 5.56 NATO and 223 Wylde can also safely fire 223 Remington ammunition. Never load it into a 300 Blackout firearm, since mixing magazines can lead to a dangerous chambering error.

Reliability and Testing

Factory ammunition from an established maker is held to consistent standards, but every firearm is a little different. Shoot at least a box through your gun before you rely on any load, and watch for clean primer strikes, smooth feeding and positive extraction. If you shoot more than one load, note where each one prints at your usual distance so you can adjust sights or holds.

Recoil and Shootability

Recoil from a 223 Remington is very light, making it ideal for new shooters and long training sessions. Wear hearing protection, as muzzle blast from short barrels can be sharp.

About Frontier Cartridge

Frontier Cartridge is manufactured by Hornady in Grand Island, Nebraska. The brand focuses on dependable, American-made ammunition for practice, training and general shooting, using new brass cases and quality bullets rather than remanufactured components. That consistency makes it easier to diagnose problems with a rifle, track your zero and build skills, because the ammunition itself is not adding variables from box to box.

Storage and Care

Store ammunition in a cool, dry place in its original box, away from solvents and lubricants that can contaminate primers. Inspect rounds for dents, loose bullets or corrosion before loading, and set aside anything that looks damaged.
