Joe, the best tip I can give you is to buy a copy of Kuhnhausen's book, "The Mauser Bolt Actions; A Shop Manual" and follow his procedures step by step. You will probably need access to a lathe and a depth micrometer (preferred) or accurate dial caliper is a must. As a rule I don't install prechambered, prethreaded bbls but I can't remember the last one I installed that actually fit. Find out if the barrel is threaded with 60deg or 55deg threads. If it's 60 you will want to chase the receiver threads with a tap. Makes final fitting much easier. Good luck with it and if you run into any problems don't hesitate to post here or give me a shout via e-mail. George
