Yes - that looks similar to the one I have...a buddy of mine who served, he was a sniper and gave it to me, it's a .50 caliber round...not a live one of course. He brought it back from Afghanistan from I think almost 10 years ago....he is quite the marksmen, somewhat famous in those circles from what I understand.
Would that also be a .50 caliber bullet Joel? I have zero knowledge or experience of firearms.....
