Hi Gary, I haven't bought any yet but these are some purchaser reviews. 1). Shot fine out of my M&P Sport II. 2). Shoots clean and accurate. I would purchase again 3). Great ammo with no issues. Highly recommend. 4). Tried this ammo; it is clean and accurate with very little smoke. I recommend this for the match shooters. 5). I ran 300 rounds of these through my M&P 15 and had no jams or misfires! Definitely will be buying more! 6). Don’t shoot nothing but this ammo on all my H&K weapons , MEN accuracy is second to none,super clean Without one single malfunctionfor the past 3 years! Grab it while still available ( usually once a year) trust me you won’t regret it. 7). I ordered a case of this stuff due to competitive price. It’s my 1st time ordering from SGammo. Am I happy I found this site . Will definitely be ordering another 2 cases. . When I received it I inspected it and the brass was nice and shinny. Shot over 250 rds through my sig m400 enhanced without any jams or hiccups. Will be ordering more in a few weeks
