So here's what I did:
- My Go Gauge is a Clymer and I put it in my RCBS Precision Mic and it indicated almost exactly on zero.
- I put this in my chamber added a dab of Lubriplate to the threads and tightened the barrel against it ever so slightly.
- I then tightened the barrel nut to 50 ft/lbs.
- I checked and my bolt closes on the Go Gauge without any resistance.
- Next I added two pieces of scotch tape to the Go Gauge and checked it again with the Precision Mic. I got a reading about 0.0035" more than without the tape.
- I put the taped gauge back in the chamber and the bolt will no longer close.
I take it I'm now good to go?
