I'm getting about 3/1000's variation in headspace of resized LC 09 .223 cases.
This is happening in the same resizing die with the same case lube as .223 Winchester brass that is being resized with ~ +/- 0.5/1000's. For both types of brass I'm using grahpite for lubing the inside of the necks.
Generally, I've found variation in resized cases similar to the Winchester brass, including other years of LC.
I'm also seeing about 3/1000's variation in the headspace of these LC 09 cases after they are fired.
The RCBS precision case mic is used to measure the headspace.
Is anyone else seeing this type of variation in LC 09?
