    ecxellent for any 5.56 rated barrel. i find that winchester brass shoots really well out of my colt and i much rather shooting brass than cheap steel

        • A:

          5.56x45 NATO ammo is loaded to higher pressures and has a thicker walled case. It can also be longer in COAL than the .223. You should never fire it in a .223 Rem. chamber. Check your owner's manual for your gun, if it says safe with 5.56 Nato, you're ok with either round. If it says .233 Rem only, than do not use the Nato round.
