Nipple size VS cap size
I have a related question. I have read multiple posts on multiple forums trying to find out what cap size I am supposed to use on a New Englander muzzle loader I recently acquired. According to the manual, I should be using #11 caps. Does not fit the nipple. I believe the nipple was replaced with a non-standard. When people are asking for nipple size, why does the answers refer to thread size? If the thread is 1/4X28, it does not affect the end where the nipple goes. or am I missing something. That beats my logic. I have a #11 nipple wrench and the hole inside the wrench is to small for the nipple to fit in leading me to believe the nipple size is not #11. I measured the end of my nipple where the cap goes. It measure 0.219 OD. What size cap should I get to fit this nipple? I purchased #12 and it is too small. I bought no 1081 FL purely by visual reference and it is too big. The way the caps are packaged, you open it, it is yours. No returns. So how do I know what to buy?
