Gents, you are dead right about the slow cooking, I just should have let it go longer. I live in Western Australia and getting black powder is not a problem at the moment. About $90 A for a Kilo of Wano (Swiss) FFFg. We do have a pretty active group of blackpowder shooters around Perth and Albany which is way down south, mostly tied up with clubs. I guess there would be a few free lancers like my self, and some would hunt as well. Most of these blokes will have a mixture of rifles, muskets, shotguns and long rifles. Long range shooting is becoming popular, with Gibbs, and PH Volunteer .451 rifles as well.
There are at least two more wabbits lurking in the garden, one is just a kitten, so will let him grow up some, and another. they are pretty shy, but will persevere.
Cheers
