shoots great, just make sure you get all of it Review by EagleEye
Quality Price Value have purchased 3 boxes in last couple of months. NO FAULT OF Weapons World.com but Federal shorted the boxes. To keep dry when out in the field I was vacuum sealing rounds in 20 round packs. 1 case had 999, second 995, third 996. No reply back from Federal on it yet.
Concern is that they should be weighing rounds for quality control to make sure not over or under charged with powder, both of which could damage your firearm or even kill you. That being said they should be able to tell how much a box of 1000 should weigh and get it right.
Low marks in quality and value because you should be getting what you are paying for - after all,.. their motto is "When every shot counts, Federal" (Posted on 2/3/12) -

Awesome product!! Review by Jim C.
Quality Price Value This is the first time I have received XM193 with the NATO cross headstamp. This is great shooting ammo!! It is a GREAT buy and well worth it. Add in Weapons World excellent customer service...........why would anyone buy ammo from anywhere but Weapons World?? I have been and will be a repeat customer.
I have noticed ammo prices going up this last week. Another reason I will be ordering more from Weapons World only. (Posted on 7/11/11)
