I purchased a custom rifle for my wife last year. It’s In the style of a Southern Mountain Rifle, anyhow she has shot it quite a bit lately and it’s now in need of a new nipple. I’ve looked through my stuff and cake up with several different sizes of nipples.... none of which fit. So I measured it and came up with this size... the shank where it is threaded is .232 thousandths with 1/4 by 26 threads. Does this sound familiar to anyone? I looked through Tracks stuff and found nothing that matched those measurements.. need help on this one. I have thought about drilling the drum and rethreading it with 1/4- 28 threads which is more common.
