yes super down is right. but your gun only uses #11 right? and since the musket is like 2.5 times hotter then the number 11 i would be a little bit worried needing that extra heat. i know of some people that use the pellets with #11 and have not heard anything. when i first started out years ago i used the pellets but with the musket caps and never had a problem with them. but they do foul more, and after my first year i went back to shooting loose and never looked back.
