I have a muzzle loader that the 1/4x28"nipple and threads have been stipper.
What would be a repair for this?
I checked around a found a oversize nipple
.284 x 28 tpi. It would be close to 9/32"
I checke msc and brownells for a tap and can not come up with one.
also checked track of the wolf?
Any help, IDEAS, appriciated.

You could get a heli-coil kit. You would have to drill and tap the hole to fit the major diameter of the heli-coil and use some epoxy on the threads.

Dixie Gun Works will have the answer for you. I know that they once had nipples in all kinds of sizes and you could use a series of nipples to recut the thread etc. They even had information on how to do this. The other idea is to drill and tap for a musket size nipple which would give you better ignition anyway.

CVA and Traditions as well as dixie gunwork have all size nipple barrels. Just replace that barrel is the easiest way.The other treads are metric. I had the same problem,just measure your nipple barrel threads and the shaft as well before ordering. van

DO NOT DO THAT!! If it fails you could get a nipple through your skull! Blind or labotimized, both are very bad. The Dixie advice is correct. They have oversized nipples and taps to go with them.
