Another head space question
I received my clymer tool head space gauge this weekend. I went to Lazerus2000 posting about head spacing with feeler gauges and went to work. First I disassembled the bolt, next I looked around until I found my ejector. :(
I closed the bolt on an empty chamber and I could get a .012 gauge behind the right lug. With the 1.630 .308 Go gauge I could get a ..008 gauge behind the lug. So this tells me I have head space of 1.638.
One posting I read said 1.640 was no go for .308 another said 1.638 was field reject for .308.
I have a Polytech from the early 90's with less than 500 rounds through it.
The lugs looked to be evenly worn.
Is this gun safe to shoot?
