I am using a Wilson Sinclair neck turning tool on new Winchester brass. I set it to turn to .012" After running an expansion mandrel down the necks I am seeing-
Some necks with very little removed.
Many necks with everything from the mouth to the shoulder removed ON ONE SIDE only.
A few with a good deal removed all around the entire length to the shoulder.
Is turning to .012" a good setting as far as case longevity is concerned? The concentricity is running from .002 to .004.
On the first 50 I turned when I worked up my loads I turned to .011, but I thought this took off too much brass. However, I did get some great groups.
I loaded 150 turned to .012, but I haven't had a chance to shoot them (in a Bushmaster) and I'm trying to decide if I want to use a Lee FCD on them.
Thanks for you input....
