Well, if you haven't noticed there seems to be a shortage of caps at the moment. I have 1000 #11's on order and a cap-maker kit on the way. I also got 1000 4-wing shutzen musket caps. My percussion rifles include a Zouave, Buffalo Hunter, CVA Hawken, Pedersoli SxS Shotgun, Traditions rifle and a Pedersoli rolling block percussion. I have musket nipples for all of them I think. I've never used musket caps before. Do I just change the nipple and keep on truckin'? More to it that that? Maybe some of these are better suited for musket caps than others? Saving the #11's for revolvers..... Thanks
