.223 is the caliber size or bore diameter of the lands, .224 is the actual bullet diameter and exactly what you want to use for .223 / 5.56mm. Bullets need to be just oversize or they won't seal the bore
Bore Diameter is actually .218 or .219 on all .22 caliber centerfires and they all shoot the .224" dia bullet.
The name of the cartridge is JUST A NAME. .220 swift, .221 Fireball, .222 Rem, .223 Rem, .224 Wby, .225 Win, .22-250, .223 WSSM, ALL shoot the same .224" Bullet.
Just like the .38 Special and .357 Magnum use the same .357" bullets. The name is just a name.
