Here are the specs: FN Mauser 98 Action Krieger #3 Sporter Contour 1:9 .284/7mm @26" B&C Medalist Varmint stock Tubbs Speedlock firing pin and spring Timney Featherweight Trigger EGW 20 MOA Rail IOR Valdata 10X with MP8 reticle Plan: 160-180grn bullets from Norma fireformed brass Here's the questions: #1. Can anybody tell me the average neck thickness of Norma .280 brass? I am considering having a custom reamer made and want to know so I can calculate optimum neck diameter and not have to neck turn. #2. Can I cut a custom sizing die with the same reamer used to cut my chamber? I plan on building a bushing type die so basically all the die would be doing is bumping the shoulder and mild body sizing. Bushings would be purchased not built. #3. I need some dimensions from the 7mm 180grn Berger Hunting VLD-length from base to Ogive and Overall length to calculate throat and COAL. Thanks in advance for the help.
