I was sorry to see the same thing, that the seal on some of the hodgdon containers gets stuck in the lid when you remove it. My main goal now is to buy powder either direct from hodgdon or a place where it is shipped direct from the manufacturer. When I used to do a pick-up in store order at cabelas, it would usually be sealed in the shipping box from hodgdon, so the chance of tampering was almost non existant.
Here's why-
About 6 months ago I contacted one of the (somewhat) local places and they told me they had two pounds of powder, one H4831 and one H4350 . So I went up and got it. The guy bagged them and I drove home. As soon as i took them out of the bag, one container felt heavier than the other. When I weighed it, it turned out to be about 1 1/2 lb of powder. When I opened it, the powder was BAD. So I had to go back and get my money back, which they refunded me without issue. Since then, I take all possible precautions, and if I do buy powder from a store, I will open it and use a flashlight to look at the powder in the container.
