Ok just seen your pic of the 2 powders and like i said thats what happend to me, I use a lot of Vit powders and all the bottle loot the same apart from the tiny number on them. I always double then triple check
I use N320 for my pistol rounds and buy in bulk. Imagine my surprise when I was getting ready to open a new bottle and noticed that it was an N310. Powder Valley had slipped in one bottle of N310 n the bunch. Since then, I check every bottle when I receive them rather than when it is time to reload.
