338 edge headspace gauge

What are people using? 300 rum?

300 Rum GO is the one for the Edge. For a NO GO use one layer of scotch tape on the base of your GO guage.

Buy a NO-GO gage, too,,,,,, and do it right!

"Do it right" with a NO GO guage? I operate at a bit tighter tolerance on a rifle set up for accuracy. Most NO GO guages are .004" to .010" over their respective GO guage. A piece of scotch tape is .002". This leaves my headspace with the tape method at nuts on to .001".

Here is some old hack doing it the wrong way like I do.

Scotch tape is 'repeatable'? There are better ways to work close to min. tolerances than tape. Your liability insurer wouldn't like the tape 'method' at all!

Shortgrass,
I think you are on the loosing end of this argument.
I think I recognize Gordy Gritter doing it that exact way in the video posted. If it is good enough for a 1000yard bench rest rifle shooter and gunsmith to do it that way, it is good enough for my rifle build.

Sorry, not into 'hero' worship. As a general rule of 'practice' in my shop I cut SAMMI tolerances in half for headspacing. I'll continue to trust my Starrett depth mic' and my ability to use it rather than a piece of Scoth Tape, to know where I'm at within that tolerance. I've got a couple of rolls in the office, couldn't find a NIST certification anywhere! By the way, I've built quit a few competition rifles in my day, too.
