I have this neat little 410 peninusla lock Cogswell with a nipple problem. I will try to avoid puns if I can.
The nipple threads are worn so that the nipples can be removed with mere hand pressure.
The obvious repair would seem to be thread restoration with a metric tool and replacing the nipples with Italian ones offered by OMPS (the Italisn equivalent of Brownnells) hence the metric thread choice.
Before I rush where angels fear to tread, anyone have any less radical suggestions? A search on the web re nipples, other than the obvious results, turns up very little info about hammer guns and plenty on muzzle loaders.
