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 long time. There is one point I would like to stress here, is, the fact military 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 specifications.
