Re: IMR Plastic Bottle Lot #s
The one that lost the sticker probably didn't lose it's sticker. The newer bottles are coming with the lot stamped on the side of the label (usually in a different color than the rest of the text). It was only for a few months that the orange stickers were found on the IMR stuff.
INcidentally, the new Hodgdon lots are being stamped on the side like IMR now.
If it's not far, it's boring.
