When they first changed over to the red/black tins, a lot of people, including myself , noticed a slight difference in accuracy. I called around and not too many sellers had gray label tins. I managed to buy a bunch and also got the Cometa pellets which were just as accurate as the gray label. I was also able to locate a bunch of the gray label 250 count tins. I still have 30-40 tins of each.
