I have a New England SB2 single shot in .223 with a badly damaged firing pin hole and pin. It appears that the firing pin somehow got bent down and damaged the hole making it severely elongated. The customer says the gun is hard to open after firing it. Imagine that! My question is which method would you use to repair the firing pin hole, Welding or bushing? I’m thinking bushing is best so I don’t need to worry about re-heat treating. Or would you have to re-heat treat other than just drawing back to a blue? I’m kind of not sure on this one.
Well welding and re-drilling is quicker and since we have TIG and can do it without a lot of heat affecting area around the firing pin hole. We would TIG it up and then anneal as you mention and re-drill and refit/repair firing pin. If you are concerned about heat affected area or don’t have TIG then the bushing method is very acceptable.
