223 Remington History and General Information:
The 223 Remington was introduced to the public as a commercial cartridge by Remington in January 1964, one month later in February 1964 this same cartridge was officially standardized by the U.S. military as the 5.56mm ball cartridge M193, several years later was accepted by NATO as the 5.56x45 NATO cartridge.
Many years of testing and development were required to produce this cartridge, the actual name .223 Remington was given to this cartridge in 1959, prior to 1959 this cartridge was also known as the .222 Special.
The 223 Remington is one of the top varmint and predator rounds in the United States. With so many variations of rifle action types, surplus ammo, range brass, bulk bullets it's fair to say the .223 Remington will remain at the top of the sales charts for a very long time.
The one point I would like to stress here, is, the fact military 5.56x45mm NATO cartridge ball ammo is loaded to different pressure levels to work in military rifles with different chamber and throat dimensions than the commercial .223 remington versions. Ball Ammo can cause higher pressures in commercial sporting rifles.
The 223 Remington is a light recoiling cartridge, easy to reload and fun to shoot, just remember to use only commercial 223 Remington ammunition not 5.56 ball ammo, if using ball ammo make sure your firearm has been altered to military chamber specifications.

Maximizing 223 Remington Rifle Accuracy:
Most .223 Remington rifles are more than capable of excellent accuracy when set up properly and shot from a benchrest. Usually the trigger on most factory produced rifles will need some adjustment to aid in rifle accuracy, of these the Winchester Model 70's are the easiest to adjust. To achieve maximum accuracy from your .223 Remington Autoloading or Bolt Action rifle there are several other things you need to do that will increase your rifles overall accuracy capabilities.
1. Properly mount your rifle scope.
2. Properly break-in your rifle barrel.
3. Properly sight-in your rifle.
4. Use this free target designed for accurate sight-ins, follow the instructions.
Note: If you follow all of the directions in the above guides that I have written, you will achieve the maximum accuracy that your .223 Remington rifle pocesses. If you encounter a rifle that just doesn't group well despite your best efforts, try swapping out the scope as this is the most common fault of rifle accuracy issues.
