Re: Pyrodex- 777 pellets
I would think that the pellets would be more prone to moisture degradation alot faster than any canned, loose powder as the containers they come in are not air/moisture tight. I do remember the old clear shot or clean shot powder that came out after pyrodex but before the pioneer american stuff that would start to degrade as soon as you cracked open the bottle. Like already posted, I have several cans of loose 777 and Shockey's Gold that I have used for the last 4 or 5 years with no noticable loss of power or ignition capability. I do however keep them in a heavy steel locker with a desicant canister to keep things nice and dry.
