RE: Question on Musket Caps
Change the nipple to a musket nipple is all that is required, but I don't think it's required.
Frankly I've never needed a musket cap after tens ofthousands of shots
RWS Dynamit-Nobel #1075 caps. Exceptional performance.
Just keep the nipple clear with a nipple pick every few shots more or less depending on how fouling a powder your shooting.
Just curious but what powder are you shooting?
