Thread: Factory Ammo Data Variance?

Context:
So I have a box of Hornady 308 American Whitetail, factory ammo, with 12 rounds in the box. However, I found 2 hornady rounds in another box of factory ammo. (Fiocchi). Now last time i was out i tested the hornady rounds and the fiocchi rounds and put them back in the safe. So I'm 100% certain the hornady rounds belong with the american whitetail ones.

But I took out my scales and verniers just for curiosity, and the OAL was all pretty similar. The overall weight for the ones still in the box were all within a ballpark, and one of the 2 i found was also within that range, but one was a good 13gr overall out.

Could that other one be a dud lighter load from factory? If so, that would really mess up someone trying to sight in.

I think ill mark it and see if the POI is different at 100m than the others in the box.
