About the Manufacturer:

Complete Quality Control
Our supplier's vertical integration philosophy allows for very reliable quality control of every PMC component each step of the way in the manufacturing process.

Because PMC's supplier produces every component in the manufacturing of all center fire pistol and rifle cartridges, it does not rely upon the quality control of other manufacturers.

All PMC sporting ammunition is produced to either SAAMI or US Military Specification standards (MIL SPEC). PMC quality control is governed by the highly sought after ISO Bureau Veritas quality certification standards.

PMC Brass and Primers
PMC ammunition is loaded in new brass cases with boxer primers. The ammunition is non-corrosive and is loaded to SAAMI specifications with the exception of 50A, 5.56X and 5.56K. Each of these rounds complies with MIL SPEC.

All PMC ammunition is reloadable. Rifle ammunition may have crimped military primers. In reloading, the crimped first needs to be removed before a new primer can be inserted. Most major reloading companies can provide a tool to accomplish this operation.

Supply Chain Management
PMC's supplier owns and operates the brass mill that produces the brass strip from which all brass cartridge cups are made.

Manufacturing all sporting ammunition in-house means not only that our supplier controls the total product quality, but also that our supplier is not dependent on other ammunition component manufacturers when shortages may occur.

About the .223 Remington Cartridge
The .223 Remington or .223 Rem is a cartridge with almost the same external dimensions as the 5.56x45mm NATO military cartridge. The name is commonly pronounced either two-two-three or two-twenty-three. It is loaded with a 0.224-inch(5.56 mm) diameter jacketed bullet, with weights ranging from 40 to 90 grains(2.6 to 5.8 g), though the most common loading by far is 55 grains (3.6 g).While the external case dimensions are very similar, the .223 Remington and 5.56x45mm differ in both maximum pressure and chamber shape. The maximum and mean pressures for some varieties of the 5.56 (different cartridge designations have different standards) exceed the SAAMI maximum for the .223 Remington, and the methods for measuring pressures differ between NATO and SAAMI. The 5.56 chamber specification has also changed since its adoption, as the current military loading (NATO SS-109 or US M855) uses longer, heavier bullets than the original loading. This has resulted in a lengthening of the throat in the 5.56 chamber. Thus, while .223 Remington ammunition can be safely fired in a rifle chambered for 5.56x45mm NATO, firing 5.56 ammunition in a .223 Remington chamber may produce pressures in excess of even the 5.56 specifications due to the shorter throat.
