There's a well known, well respected silhouette shooter in the States called Chuck Raithel. Cybershooters who visit "Shooters" will know him as Coydog. He's produced a guide to loading the black powder cartridge which also contains "pet" loads of various shooters on "Shooters". He's, very graciously, allowed us to make it available as a download from here. It's available as either a Microsoft Word© document or as an Adobe PDF© document. It's well worth the read!
