nipple repair question

[slowtrack50cal]

Hey all.  I have cross-threaded the nipple in my Plains Pistol.  The nipple is unharmed, but the threads in the barrel are messed up.  Is it possible to remove the top two threads with a drill bit and still have a safe shooting weapon?  Any thoughts?

I think that would leave about 5 threads or less.  I would not feel comfortable.  If you have room you may consider a 5/16-24 nipple.

MBS and others sell oversize nipples & taps, simply choose one a size or two up from where you are and carefully run the new tap into the old hole, install the new nipple.

This is why breeches should be harder than the nipple.
Does the nipple even engage the top 2 threads when seated?
Many are rebated and have about a 2 thread gap at the top of the threaded portion.
The threaded portion only needs to be 1/4 long for max strength.
But I also hate blowing out nipples. One reason I shoot flint.
RETAP DO NOT DRILL.
If you cannot be sure of tapping the top 2 threads without damage find someone who can.
