Batchman, the Gun Runner extractor is made for the standard length Mauser action. Brownells has two version, one for the standard case head and one for the magnum case head.
A magnum length extractor is 0.4" longer than the standard length extractor. The standard Mauser action is 8.75" in length and the magnum Mauser action is 9.15" in length.
Brownells could not provide the magnum length extractor. They did give gave me Gun Runners phone number. I haven't called them yet.
