Ammo worked well in my Barrett M99, ran through the gun well, and no FTF's (fail to fire) yet! Brass is re-loadable and I give it a B- on the cleanliness of the brass. Free ammo box is also nice, It will hold around 200 - 250 of these bullets! This is my 4th purchase, and I will continue to buy!
For the money it shoots as good as, if not better than the Barrett M33 Ball out of my Barrett 95. Save a few bucks and give this stuff a try....great for reloading too!
