Thanks for all the replies. I do have the 209 primer kit for my Super 91 but have never tried it because I never had any trouble with the #11 caps when using black powder. I was concerned about ignition with the #11 if I ever tried a black powder substitute. I'm going to give the triple 7 a try. Still trying to figure out a good 50 caliber bullet though. I like a pure lead conical bullet. Are the Power Punch bullets still being made?
