Lyman has some blackpowder rifle/pistol kits. They come with precut wooden stock, barrel, all the parts, predrilled and such. You just have to do the fine work for sanding, the bluing, stock staining/finishing, any painting/checkering. It came with the chemicals/stains/stock finish. About $100-150 less than buying the assembled version. I did one years ago in .54 cal rifle. Is this the kind of kit you are looking for?
