I just came across 2 lbs. of IMR3031 for free. It's in the old metal can (see pic) It's been properly stored and should do fine in my 308, but I got an uneasy feeling about it.
It says "formerly supplied by DuPont" on the top of the can (visible in pic) I just want to be sure this is the same stuff that now comes in the plastic jugs. IMR still lists a charge for it. Any reason why I shouldn't give it a shot?
