just did another interesting experiment. Took a piece of previously fired and unsized brass from that gun and it took .005 worth of shims to reach a no go condition. Then I took a piece of new Winchester brass that has been fully resized and did the same thing with the same results. Yet using the head space gage it is set correctly
My head is starting to hurt now.
Well at least know the head space is now correct. Go gage and the bolt close with slight resistance at the botton. .001 shim and bolt will not fully close .002 shim and bolt will not close at all
If I get another case separation or see anymore light rings on those cases I will pull the powder and bullets from whatever is left unfired and recycle them all
