New Staball Powders?

[clearwater]

Looks like Winchester is making a faster and a slower version of their Staball Powder. Anyone heard about them?

Not much they are now listed on there webpage though one is called StaBall HD looks to be a slow burning powder for big magnums and there is StaBall match that I would bet is some where in the slower burn rate 308/223 burn rate range as it’s listed for heavy bullets, think 68-80gr for 223 168-180gr for 308
