One of the clubs I'm in has lot of black powder comps, for everything from revolvers and single shot pistol to muzzle loading and BPCF rifles. Personally I only enter the revolver comps as that's all I've got. For revolver comps they have to be spirit of the original so I can only use my 1860 Army. Which is bad for me as I can't shot my Ruger Old Army very well with its adjustable sights, so you can imagine how bad I am with the 1860 Army
