223 (5.56) Ammo
.223 Remington ammunition and 5.56x45 NATO are closely related and sometimes interchangeable cartridges depending on the firearm they are to be used with. Manufacturers typically offer guidance on this point. In general, the 5.56 NATO ammunition the military uses and is for sale to the civilian market operates at higher pressures than .223 Remington ammo. Most, but not all, AR-15s are chambered for 5.56 NATO and can fire both types of ammo.
Many loads in both calibers follow the M193 or M855 standard, both of which are military specifications. M193 ammo typically fires a 55 grain full metal jacket bullet at 3,240 feet per second, while M855 ammo fires a heavier 62 grain FMJ bullet at about 3,100 feet per second. These common standards are very helpful when sighting in your optics and you'll find both cartridges in-stock and available in cheap bulk packs here at Widener's
Certain specialized loads deviate from these common standards. Competition grade .223/5.56 ammo fires a heavier bullet (most commonly a Sierra MatchKing) in the 77 grain range to provide better stability and more predictable trajectories; varmint loads, on the other hand, fire light 30-40 grain bullets at very high velocities to produce lethal fragmentation against pest animals.
One of the most sought after range loads for this caliber is Lake City ammunition, which is produced by Federal Premium Ammunition at the Lake City Army Ammunition Plant in Independence, Missouri. LCAAP production is typically excess from government contracts and is popular due to its military origins and high quality.

Remington UMC Freedom Bucket 223 Rem 55 Grain FMJ – 300 Rounds
$164.85Product Type Ammo Manufacturer Remington Condition New Bullet Weight 55 Grain Bullet Type Full Metal Jacket (FMJ) Use Type plinking at the range Casing Type Brass Quantity 300 Ammo Caliber 223 Remington Manufacturer SKU L223R3BC Primer Type Boxer Magnetic No UPC Barcode 47700471402 Cost Per Round 54.9¢ per round This 223 Rem cartridge from Remington’s UMC line of ammunition is a great way to keep your AR-15’s barrel hot all day long, but without breaking the bank. UMC only makes ammo according to Americans’ favorite specifications, so while their offerings may be limited they’re able to add a great amount of value to them. This round’s 55 grain projectile is technically the metal case variety, but that’s essentially a five dollar phrase for full metal jacket. It’ll keep your bore cleaner in order to maintain its accuracy, and feed without flaw in a semi-automatic as well.
This round further features a reloadable brass casing, sensitive Boxer primer, and propellant that burns clean to keep your rifle’s sensitive inner parts intact in the long run. You get these 300 cartridges all together in a big plastic bucket -- the Freedom Bucket, to be specific! Such a tub is great for sharing with friends, and makes a fine receptacle for spent casings and future loose ammunition purchases alike.Customer Reviews
