Description

Federal 223 Rem 55gr FMJ 500 Round pack is what most people buy when they need to feed an AR-15 rather than impress anyone. Federal catalogues it as FC223F500: five hundred loose packed rounds of 55 grain full metal jacket leaving the muzzle at 3240 fps for roughly 1280 ft-lbs. Brass cased, boxer primed and reloadable, which matters when you are buying five hundred at a time.

The Default AR-15 Practice Load
Fifty five grain FMJ is the reference load for the .223 Remington. It is what most rifles are zeroed with, what most gas systems were designed around, and what practically every drill, class and club match assumes. There is real value in that: your training ammunition behaves the way the rifle expects, and your zero and holds transfer to whatever else you shoot.
Five hundred rounds is the right quantity for anyone who actually trains. A carbine class burns three to five hundred rounds in two days, and a serious range session with drills goes through two hundred without trying. Buying 223 Remington bulk ammo by the five hundred means you stop rationing rounds, which is the single biggest thing that improves most shooters.
Brass cases are the quiet part of the value. Five hundred pieces of once fired Federal brass is a genuine asset if you reload, and it holds up well through multiple firings. Even if you do not reload, brass sells or trades, and it is one reason a brass cased bulk pack is worth more than a steel cased equivalent at a similar price.

This is loaded to .223 Remington pressure, which is safe in both .223 and 5.56 NATO chambers. Federal packs the rounds loose in a bulk box rather than in individual trays, so expect to sort them into an ammunition can or magazines rather than storing the box long term.

Honest Notes on Bulk 223
This is practice ammunition and it is not pretending otherwise. Expect two to three inches at a hundred yards from a decent AR, sometimes better and sometimes worse depending on the rifle and the lot. If you need sub minute groups, buy a match load. What Federal 223 Rem 55gr FMJ 500 Round pack gives you is consistent point of impact and consistent recoil so that training actually transfers.
Chamber compatibility runs one way and it is worth being precise. .223 Remington ammunition is safe in a 5.56 NATO chamber and in a .223 chamber. It is 5.56 ammunition in a tight .223 chamber that raises pressure concerns, not this. So this load is the safe choice across essentially any modern .223 or 5.56 rifle.
FMJ is not a hunting bullet. It does not expand, most states prohibit it for deer, and on coyotes it tends to pencil through. Keep a box of soft point or polymer tipped ammunition for the field and use the bulk pack for the range.
Storage matters with a loose packed box. Five hundred rounds knocking around in a cardboard bulk box will pick up dented case mouths over time. Transfer them to an ammunition can with a desiccant pack if you are storing them for more than a season, and glance over them before loading magazines.
For a varmint load in the same calibre see the Remington 45 grain JHP bucket, and the Underwood 62 grain Controlled Chaos is the premium hunting option. Full product data is on the Federal Premium website.
