If one uses Swiss 1½FG it will get as close to the original Curtis & Harvey blackpowder. I friend of mine here in Denmark uses it for his .500BPE loaded up with 135grain to a 440grain paperpatch bullet. It will get right up there duplicating the factory ballistics(1800 ft/sec).

ditto - Swiss powder are said to be much closer to duplicating the old 'old' Curtis and Harvey powders used for regulation of English guns - according to Seyfreid and others.
He found GOEX needed up to 20% more to match Swiss. In most or many cases, that just isn't possible.
