Hears the deal, I have a rem .243 adl. The fired cases measure 1.625" with a stony point headspace guage. My go guage measures 1.617 and the no go guage measures 1.621. My fired brass is .004 over the no go guage and the chamber is probably a little more than that. I figure the gun is defective. Well I try the no go guage in

.243 win coyote less than 100rd
2 different ruger .243 both less than 100rd
rem .308 vs, new unfired

the bolt closed on the no go guage on all of them
Sooooo, whats the deal? It would have to be a coincidence of coincidences for all five guns from 3 manufactures to happen to be defective.

An unfired rem brass measured 1.620 so I am thinking the guages must have been on the very min of tolorances. I am lookin to get a field guage, but mid way does not cary that one.
Ideas?
