When possible I like to have musket nipples installed on my BP rifles. I prefer the extra umph to ensure reliable ignition. Recently I picked up 2-3 TC Hawken style rifles but wasn't able to find the nipples in local stores in a 250 mile circumference from my house. I know I could have internetted them but wasn't yet that desperate. Walked into a gun shop in Salmon Idaho while out that way fly fishing and camping off the back of a Road King and ran across them. CCI Musket Cap and nipple on left. #11 cap and nipple on right. Respective cappers in background for scale. From the business end: Musket Nipple on left. #11 Nipple on right. Installed Musket nipple: Seats and lines up nicely on this .45 cal TC: For in shop work a good selection of decommissioned dental instruments comes in very handy for cleaning out nipples and nipple drum/flash channel.
