Tom , soft soldering sights on would be a good idea, particularly as the bore is not parallel to the outside. I am still working up a load for my Forsyth rifled bore gun, I found mine quite comfortable to use with 4 1/2 drams of Fg. I am going to work up some loads with FFg and see if I can get a better group. I as Darryl suggested use a thick hard felt greased wad over the powder, helps with loading and does a good job of protecting the patch. I think also it my help the combination to engage the rifling, mine is an original rifle and the bore is not quite as nice as it could be. Look forward to seeing the finished rifle and a target or two !!

Cheers
