[QUOTE="woods, post: 286471, member: 6042"] Not trying to spend your money but you will get better measuring results with a ball micrometer and a stand [IMG]http://img.photobucket.com/albums/v663/bwestfall/CASE%20PREP/DSCN0727.jpg[/IMG] if you already have one then you know what I mean. So taking the larger measurement of .316": .316"-.284"=.032"-.003"(clearance)=.029"/2=.0145" and you can just clean them up but if it is .313": .313"-.284"=.029"-.003"=.026"/2=.013" and you will need to do almost a complete turn. On a recent thread here nheninge posted a drawing which showed why brass with a thick side and a thin side are not the best and will still produce runout even with a complete turn [IMG]http://img.photobucket.com/albums/v663/bwestfall/CASE%20PREP/neckcenter.jpg[/IMG] [/QUOTE]
