NORMA Brass - 223 Remington – New and PRIMED - QTY 100
NORMA High Performance Brass Cases – Unmatched Reloadability - Unprimed
Shortly after the introduction of the .222 Remington experiments began to make a similar cartridge for military use. The advantages were obvious as a soldier naturally can carry many more rounds of a much smaller and lighter cartridge. Drawbacks was the reduced long range potential of the smaller bullet and its lesser penetration. 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, but with a heavier 63 grains bullet which demands a quicker twist (1 in 7”) than used in most sporting rifles for the civilian market (1 in 10, 12 or 14”).
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. Due to the adoption by NATO the .223 is expected to be the more popular choice in a few years by European shooters.
- Neck – Annealed to achieve proper elasticity and prevent splitting, NORMA cases are then put through a final polish process to ensure superior appearance in addition to superior performance
- Shoulder – NORMA applies over a century of experience and proprietary tooling to ensure dimensionally perfect headspace
- Body – Laboratory Inspection ensures proper hardness over the length of the case; softer at the neck, getting progressively harder towards the case head.
- Tolerances – In-house tooling production allows NORMA to not only control tolerances of the finished product, but of the production tools and machines themselves. With tooling tolerances down to 7 thousands of a millimeter, NORMA is proud to have the tightest tolerances in the industry
- Flash Hole – Three quality control inspections for the flash hole ensure a perfect centered and burr free product. Bench rest quality in every case!
- Primer Pocket – Proper hardness of the primer pocket is critical to long case life. At NORMA, each production run is tested to a minimum of ten reloading cycles.
- Primed (but not crimped).
