I never have tried to shoot over 500 yards with a .223, and I don't know what a 224 looks like, please remember I'm doing this for the fun and to learn something, it's not life or death to me. Rio7
.224 is the standard bullet size that "22" caliber centerfire rifles shoot. 223, 222, 22-250, 220 swift, etc all shoot .224 caliber bullets.
