I had 8lbs of H4831SC (all same lot number 5195) and I just opened them a few days ago and put them all in an empty 8lb container. I thought this was going to work for my 6mm but it's just a little to slow burning. So my loss is your gain. Fresh 8lb jug. Looking for $190 FTF. I bought these for $28/lb so this is a pretty good deal. First come first serve. No trades. Don't low ball or I wont even respond. Thanks!
