[QUOTE="tobnpr, post: 1977079, member: 68758"] Personally, I would have no problem using the fired/sized brass as a quick and dirty way to check the headspace. More care is needed as brass will easily distort where a ground/hardened gauge will not. Completely stripped bolt so there's no resistance from spring, extractor or ejector. Bolt handle should fall with no resistance or VERY light finger pressure on fired case. Add a layer of cellophane packing tape (usually about .003- but mike it to know what you have) trimmed with a razor to fit the casehead. If bolt handle still falls with no resistance, add another layer of tape. This will get you to something around +.006 depending on the thickness of the tape you're using. Bolt handle should not fall with reasonably "tight" headspace clearance. [/QUOTE]
