Antique Nipple threads

[Cajun72]

Well since I recently acquired some Antique rifles made in the US. What is the most common nipple threads so I can try and find some new nipples?

Go to the Track of the Wolf page and search on that term, as they have them listed for what fits what. That's the resource I use honestly ...

Note that Whitacre Machine Shop makes over-sized nipples in case you want to restore one to shooting condition and the existing thread holes are buggered up.

Well removed the nipple from my WM Gardner Rifle. 1/4-28 is close but a little loose? I can't find my thread pitch gauge.

Get a short length of soft dowel rod and thread into the hole. You can measure from that, enough for an estimate. Don’t break it off in there!

Possibly a #14-28, or the old standard .255-28.

When needed I have used the oversize thread nipples from Dixie and Track of the Wolf for the original guns.
Track seems to have a better selection now and the appropriate size taps for thread cleanout.
