SOLD/EXPIRED Looking for a 300 RUM no-go gauge

You don't have a piece of .004" shim stock, or scotch tape?
I put tape on the back of my go gauge and it took .009 to make it so the bolt wouldn't close. Looking at the Saami specs there's .010 difference between minimum and maximum case dimensions. I'd like to be absolutely sure that I'm in the safe zone.
 
I'd go against saami on this one, that seems like it's getting pretty loose. +.003-.004" is the common no go, and .008" is a field gauge. I don't think you'd have a separation at .010", but couldn't be good for case life.
