Always been confused about that myself. Especially since W231 is said to be the same powder as HP38....which I use often. HP38 certainly isn't a "ball" powder. But, "squished ball" makes sense. The flakes (of my HP38) look like they could be something like that - and W231 and HP38 do look exactly the same.
I read the link (on the Winchester website)..... "ball process".....now it all makes sense !
