Saw that. Interesting stuff. Swiss BP today, is the best as far as power per grain weight is concerned.
Some of the BP Ctg. shooters like 1.5 F over the older GOEX or the newer Schutzen powder out of Germany.
I am currently shooting Schutzen 2F along with Old Enysford(GOEX) 3F in my ML guns.
I use either GOEX 1F, or Swiss 1.5F in my Sharps. It doesn't care which is used & there is very little change in POI.
Not sure on the Federal Laws about making BP(Class A Explosives) here.
