Re: WC867 Military 8lb Keg
Not that this helps but an unnamed supplier of Milsurplus powders mentioned that a particular lot they were selling was from a foreign arsenal. Most US Mil sourced reclaimed powders are stored properly- I would hope- but one never knows the true history of Milsurplus stuff. Foreign nations don't have high standards like our military.
I have purchased foreign sourced pistol/ subgun ammo that was truly bad and degenerating. Had to pay close attention or shooting a full power round after one stuck halfway down the barrel ringed the barrel then and there. On a registered Title II Thompson M1A worth $18k the money saved didn't seem a prudent choice....
