Hello All,
I have some fire formed brass that hasn't been put through a die yet and hasn't even had the primers removed.
I'm using a RCBS Precision Mic to measure the headspace and I'm getting a variance of 1.5-2 thousandths on the measurment between the brass.
How can that be? Shouldn't it be much tighter than that since it's fire forming to a chamber?
