Our Norma Primed 5.56x45mm NATO brass cartridges are of very high quality and incredbile value.
Shortly after the introduction of the .222 Remington, experiments began to make a similar cartridge for military use. That cartridge eventually became the 5.56x45mm NATO. The first .223 appeared in 1957 and was mainly the work of Robert Hutton of Guns & Ammo and Gene Stoner of Armalite. One of the requirements for the new cartridge was that it could retain a velocity exceeding the speed of sound at 500 yards. This was not possible with the .222, but with its slightly longer case and a 55 grains boattail bullet the .223 met the demands. The cartridge was adopted by the U.S. Army in 1964 and used in the Vietnam war. Since then it has been adopted by NATO as a standard military cartridge.
The dimensions of military chambers and cartridges vary slightly from the sporting version that was brought out by Remington shortly after the .223 was adopted by the military. Accordingly military ammunition might produce high chamber pressure in sporting rifles. Military cases quite often has thicker brass and starting loads must be reduced by at least 10 per cent.
For sporting purposes the cartridge is normally at its best using bullets of 60 grains or less. It is suitable for the same range of purposes as .222 Remington, and will add some yards to the effective range.

Great quality for a fair price. I have reloaded some of this brass 4 times already. It has performed well and is showing now signs of wear.
Extremely pleased with this order. Will definitely order again.
First off, I am primarily an hunter, not a competitor. For my purposes this is very good, especially at the price. I ordered 200, weighed, measured neck thickness variation and checked to make sure the lengths weren't over maximum. None required trimming. All but one fell into a range of 103.2 - 104.6 grains. The outllier is 102.7. Most had no more than .001" neck thickness variation. Forty had neck thickness variation between .001 and .002". Only two had a variation of over .002". For my uses all but three of these will be great.
Looks like the Norma 556 is laser engraved on the bottom. Brass was shiny and all 1.54 inch. Amazing SD of 4.1 on a gas gun 556. Def was worth the price being new brass and primed for half the price of quality unprimed brass. Plus it was at my door in like 2 days.
