Who made the 7 groove, 7 land round bottomed rifle barrel? Looks like it has a very shallow crown and not funneled or coned. What does Jud recommend feeding it? 90 grains FFg with .610 round ball and .015 thick patch? Like how high he pinned the pivot for the simple trigger. Good geometry and should be right there when tripping the sear. Is it Colerain or Rice that has a gain twist black powder barrel? Maybe someone else.
