My uncle has a T/C Hawken that the nipple threads are stripped. Is there a slightly bigger nipple thread size that I could drill and tap it for? Its a 1/4-28 now. Thanks

Check Track of the Wolf.
They list them by thread sizes.
To go larger , you may want to tap it for a Metric thread just to be taking out minimal material if needed
They also make Oversized threaded nipples if you thread is not totally gone
Ok. Thanks. I've not seen the condition of the threads yet. The threads may not be stripped completely out. I thought about drilling and tapping for an insert but, don't know how much metal is around the hole.
If it is 1/4-28 Helicoil is an easy option.
When you get the rifle, Run a 14/28 bottoming tap into the hole.
If you don't have a Bottom Tap , then just grind off some of the end of a regular Tapered Starter Tap.
That will guarantee you are into the Full thread area of the Tap because of the restricted depth of the breech plug hole.
Then you can decide if the oversized threaded Nipple will work.
But I bet it will.
I have rarely seen a TC with the threads completely gone , or totally screwed up.
I've got helicoils which we call threaded inserts. If I can't run a bottoming tap and fix it, I'll try the insert. Hopefully theres enough meat there.
A friend brought me a rifle one time and get said the nipple hole was stripped because the nipple wouldn't tighten.
The threads on the nipple were fine.
But when I checked things out , he had just put the wrong threaded Nipple in the rifle.
He had somehow got a Metric nipple from one of his other rifles mixed in with his standard thread nipples.
I cleaned out the nipple hole with the right tap , then put in the correct nipple.
That might be something for you to check also.
Lags might have it ---you woiuld do well to check that out - there is a no 12x28 unf thread that is very difficult to pick from a 1/4 x 28 ---plenty of nipples out there are no12 x28 and that is a loose fit in a 1/4 x 28 --we had that same problem with a Walker colt my son bought second hand - prior owner had put a new set of 12x28 nipples in - the cinched up tight when they bottomed out but the threads were loose enough to show some powder erosion all the way ---not an ideal situation !!! a set of 1/4 x 28 cured the problem.Quote:

The nipples listed as 12-28 were used in a lot of early Italian cap and ball revolvers and I have 3 that use those nipples. They will slide right in a 1/4-28 but can even blow out! If the threads in the snail are damaged I would not try a thread insert since there is not a lot of metal to have the threads grab. A better solution would be to replace the hooked breech plug with it's included snail and then all is brand new. They are available from T/C, or used to be.

Ok, like I said I've not seen the rifle yet, and haven't checked anything, But, I was concerned that if I had to insert it, that there was enough metal around the hole. I may just try and find the hooked breech plug. Thanks.
