I am setting up a brand new RCBS Summit press with Redding competition dies for 308 using a .336 bushing.
After getting the neck sizer setup I am getting 8 thousands of runnout on the case neck on my once fired cases. Before they are sized at most they have 1.5 thousands so it is the neck sizing process that is doing it. I have tried using the body sizer afterwards and it changes nothing. After neck sizing I tried turning the case 90 degrees and no luck with that either.
What am I doing wrong??
Thanks, Sammy
