Frank,
That was what was kind of banging around in my head. Manufactured by Wano.
Several years ago, I tried some Wano and frankly, I was less than impressed. As I recall, the fouling was much harder than GOEX and I did not get as good a velocity with comparative charges as I did with GOEX.
Now, granted I was playing with one of my big bore rifles, and was using maybe double or more what would be used in a .50 or .54, but that was my read on the powder. Didn't care for it. YMMV with a smaller bore gun.
The can was pretty slick, though. It was a round can with a funnel shaped top. All the powder would pour out of it quite easily.
