Well I got my Lyman GPR 54 percussion a month or two ago and I was able to find some FFFG Goex in west Arkansas to shoot it but I was thinking I would go ahead and order some powder from Graff . In order to justify the HAZMAT fee I really need to buy about 5 cans of the Graff Brand Powder . So my question is should I order FFFG or FFG . There seems to be no rime nor reason to what people are loading when I read this forum. Lyman says FFG but I would appreciate you guys offering your reasoning.
