Would also trade straight across for shotgun powder.
I'm relatively confident I can use this in 28ga, but not desperate enough to spend $50 for pressure testing yet. Will probably end up just doing that eventually worst case.
The truth is I thought about giving you the jug of Universal. But, even though it's not my first choice of powders for most of my loads, it has many more applications than WAP.
I have a couple 1 lb jugs of some of the powders you listed, but again they are a preferred powder for my loads. Sorry.
