Problems with Lake City being Under Powered?

[Funner]

Have any of you experienced using Lake City ammo and having quite a few of under powered rounds? Through one mag at least 10 sound like duds. And with a mag at least 1-2 rounds fail to eject and cause a stove pipe or a similar jam.

I will let you know the exact model bullet/ammo.
It was bought in a number of 1000 round bulk buy's.

Thanks

The ammo is Federal American Eagle, 90 rd Black box, On stripper clips, 5.56 nato, 55gn FMJ, 3165 fps, XM193AF90,

The stamp on the casing has a LC and a 14 I am guessing a 2014 date of manufacture.

I've never had an issue with their (or anybody's) 5.56 M193... only with .223 variants.

any chance the rounds got contaminated in the mag or on the strippers??
