The .223 Remington is one of the most widely used centerfire cartridges today. Tracing its roots back to the .222 Remington, the .223 was designed to achieve certain ballistics for military use. The .223 Remington, when in its military form, is known as the 5.56x45mm NATO. The differences between the two being the pressures that they are loaded at and the chamber in the firearm itself.

The .223 has established itself as an excellent varmint and target caliber. It dominates all other rifle calibers in competitions such as 3-gun, and has a dedicated following in several other sports due to its low recoil and accuracy potential. Those two attributes coupled with good velocity allow it to excel as a varmint gun also.

When loaded at .223 Remington pressures, our brass is safe to use in any firearm chambered for .223 or 5.56x45mm. If loaded to 5.56 pressures, you need to use firearms labeled for use with 5.56mm. It can be unsafe to fire 5.56mm ammunition in firearms with a .223 Remington chamber.

(for "Wildcats")
1.780 - 1.810 O.A.L.
This brass is the same as our standard .223 Remington brass except that it has not been formed and has no caliber designation on the headstamp. It should work perfectly for most .223 Remington based wildcats. This brass has not been annealed, and will require a body anneal prior to forming, and possibly a neck anneal after forming, depending on how far it is necked down. Wall thickness at the mouth of this brass is approximately .009", which is the same as our .223 brass prior to forming (the walls will get thicker when formed down, and the case will also get longer). Length is approximately 1.800"

*Since this is a basic case, and Starline has no control over how it is formed, we accept no liability and offer no warranty in its use or your inability to properly form cases. Since this case has not been formed there may be more out-of-round mouths than normal.

Calibers that this could possibley be formed into: 6mm TCU, 6.5 TCU, 7mm TCU, 6x45mm, .25-45 Sharps, 6mm Mongoose, 7.62x40WT, 7Raptor, .357 MAX AR, etc.
