hi guys ,i just got a stevens .308 win. this is going to be a project gun with my first barrel swap, followed by new trigger, magazine conversion and stock. i need some help from you guys; i have done a search on this site and can no seem to find what i am looking for. can someone out there please list the steps in the re barreling process in detail? when do you set the headspace is one question i have. how do you go by setting the headspace? i have ordered a PTG guage from midway along with the 20" barrel, and new barrel nut. i have never done this before so the more you can tell me the better off i will be.

thanks guys
