This is an interesting discussion on setting up dies and FL vs NS from BR central and some of the top gunsmiths and shooters in the game gave their insights of years of building and shooting LR rifles. Note the comments by George Kelby and Dave Tooley below. I will admit, I often set up dies for match guns a little tighter than hunting guns (.002 max). I have had hunts ruined with gun failures early on and do not want to go there again. Brass is cheap and hunts are not. I am betting 90% of the shooters do not even have a firing pin removal tool for all the actions to even run the tests the proper way. Cost is under $50 and you will be surprised how much easier it makes your life in reloading for accuracy and reliability. The "click" when extracting a case? Anyway enjoy and print off a copy to keep with your reloading equipment and if you disagree go to BR central and tell them why they are wrong.
