OK,clean and brief as possible (ok, embellish a little):What firearms can fire BOTH the 5.56mm and the .223 Rem? and which are limited to the .223 only?Thanks,Carlp.s. I am strongly considering a Savage in .223, and don't want to spend alot of time worrying about my ammo. besides, some NATO surplus is cheap right now.-Carl

  Short & dirty: HUH? Embellishment 1: dimensionally, these are the same, just different names for the same cartridge, think .308 Winchester & 7.62x51 NATO. Regardless of the verbiage, the chambering and the ammo are interchangeable.Embellishment 2: If you are talking fine accuracy, there may be rifling twist differences, action variables or other factors in which the bullet weight, standard velocity or other factors could play a roll and I'm not qualified to advise in that respect.

  The throats of 5.56 are about 0.025 longer to handle the M856 tracer round.For practical purposes there is no difference.cpermd
