Goex Cowboy

[Slamfire]

This is supposed to be the hot setup for charge weights below 40 grains. Marketed to SSSA shooters primarily, it shoud work in muzzleloader small bores as well. A bit quicker burnin' than Cartridge grade and a bit slower'n FFFg. Has anybody tried it in their squirrel rifle?

I have not tried Cowboy but I had contemplated switching to GOEX Cartridge. According to GOEX, it's grain size is between 2f and 3f.

GOEX says if used over 40gr, increased fouling will occur. Why is that? I'd be curious what it's grain size is.
