Home Forums Hunting & Shooting Gunsmithing Checking headspace without gauges?

With a mauser putting the safety in the center locks the
firing pin out of operation. The extractor has nothing to
do with the measurement. Put a NEW CASE under the extractor
and insert the bolt. Add tape until you can just feel the
shoulder touch. Tape runs around 0.002 in, you can mike it
if you want a better measurement. This is a measurement of
the headspace with that particular case.
