DaveP3@ said:You can use NATO ball in civi rifles, power really isnt an issue as the case can only hold so much propellant, its safe to say a .223 rife will be fine with mil spec ammo as long as its chambered correctly (5.56x45)
I put 100's of rounds of mil spec ammo thru my club guns without a problem.
This man speaks the truth. There is no problem firing NATO rounds through civilian rifles. To all intents and purposes, they are identical.
