Ive done M16 extractor installs before on 700's with standard and magnum bolt faces. The process goes: take a standard bolt face factory 700 bolt, open it up, solder a nose ring, face the new nose, bore the bolt to a .223 bolt face, then cut the extractor groove. This has worked just fine with standard and magnum bolt faces, but when you bring it down to a .223 bolt face, the new nose covers up part of the ejector hole. How do you go about locating and clearancing for the ejector?
