I am experiencing a problem reloading a .7mm Rem Mag with Redding F/L and Neck Dies. I reloaded some Berger 168 VLDs and after pulling one of the bullets with a kinetic puller noticed that the area of the bullet that was seated in the case neck area had been squeezed down to .279. The area at the beginning of the boat tail remained .284 and the area above the neck also remained .284. A sized case neck O.D. diameter measures .309 and the neck wall averages .014 The neck expander button measures .2825 I'm puzzled why the bullet diameter in the neck area is being squeezed down to .279. Clearly this is hurting accuracy even though the VLDs have a long ogive. Any help will be appreciated.
