My friends:
To "accurately" set the headspace in a rimfire gun one should remove the extractors and the firing pin assembly from the breech bolt.
I even remove the indent ball and spring from Shuls and Anschutzs, although I believe one could get by without this step.
Setting accurate headspace is like using a micrometer.....the tension placed on the breech bolt by the firing pin spring and the extractor springs makes it impossible to accurately "feel" the gage.
I had a friend of mine set the HS on his 2007.....he set it at .043"....with the extractors and firing pin in place....The rifle would shoot some amazing groups but he was having flippers.....he brought the rifle to me and the first thing I did was to check the headspace. It would just barely accept a .040" gage, with pressure on the bolt handle, after I removed the extractors and firing assmebly.
I re-set the headspace, "correctly" at .043" and the flippers stopped.
MY friends, having said all the above, it's your gun, you of course, can set your headspace any way you want.........
