What type of caps are you using? They do vary some. I prefer the Remington caps on my guns. I have a tin or 2 of the CCI caps and they are just a pain to use and don't go down onto the nipples enough to be seated. (has caused me loose a deer also) I would do the emory cloth but that would require me to do 14 nipples. 2 for rifles and 12 for black powder pistol. Just easier to use a different brand of caps.
