Putting a new barrel on my 308 LR gun and I want to make sure I get it throated correctly. My current barrel is throated so that with .010 jam, the bottom of the boat tail is about ~.050 above the shoulder-body junction of the case. I would like to have the bottom of the boat tail just below the neck-shoulder junction, and that would leave me with ~ .015 of the bullet bearing surface in the neck. I guess I am concerned with turbulance created around the boat tail area. I am also extremely anal.
