[QUOTE="Kevin Cram, post: 462228, member: 2215"] Shortgrass, you must not understand the scotch tape method for a NO GO. I don't even own a NO GO gauge, they're useless and too far on the other side of the tolerance range. If you chamber to what your headspace measurement calls for and check it with your depth mics, I'm sure you then screw the action on and try a GO gauge to make sure the bolt closes. If it closes fine and your at 0 headspace according to your depth mic, remove the GO gauge, clean off the base of it and attach 1 layer of scotch tape. Trim the excess off with a razor blade. You've know taken your GO Gauge and made it .002" longer. The normal NO GO Gauge is any where from .004" - .007" longer, you've just tightened up your tolerance range. Try the gauge now and the bolt should not close. This now tells you your headspce measurement is anywhere from 0 - plus .001" Try it once I'm sure you'll find it handy. [/QUOTE]
