I recently received a "new to me" .45 cal T/C Hawken. This rifle has needed A LOT of work, but I'm about ready to take her to the range. I've had to replace the standard 1/4X28 T/C nipple with a 5/16x24 thread size due to the threads being narly-nasty. My problem is, I need a shorter nipple than what I currently have. The Treso Ampco nipple I was going to use is .753 long and does not allow the hammer to come into half cock nor does it totally clear the nipple head. A foctory T/C 1/4x28 musket nipple measures .582 in length and would work perfectly, if it were the correct thread size. Track of the Wolf and Dixie Gun Works has a pretty good selection, but everything listed is long. I was hoping some of you good folks could tell me where I would be able to purchase a nipple that will work for me? I would like to use a musket cap over a #11 cap. Thank you for any assistance you guys can provide.
