Shooting a .243 w/ Lapua Brass, and due to my loathing the expander ball, I want to have Forster custom hone a die for me. Strictly a hunting rig, so need enough neck tension so that bullets won't move in the magazine under recoil. Currently my loaded ammo measures .271 - .272 at the neck. Figure I need .003" tension, and allowing .002" spring back, that comes out to a .266 to .267" die. Is my reasoning correct? My once fired Lapua brass measures about .277" prior to re-sizing. Does this figure into what neck diameter die I need?
Thanks,
John
