I'm a 100 yd BR shooter that generally shoots in the 1s and am thinking of getting a Cambridge V4 Autotrickler/FX-300 powder measurer/dispenser which I think can very precisely measure powder loads with the intent to help reduce group size. However, I don't know if there's a point beyond which increased powder measuring precision no longer helps translate to smaller groups in a tuned BR rifle. Has anyone compared group size from rounds loaded with various BR tricklers/scales with a range of weight measuring precision to see how precise powder measuring equipment needs to be before it's precision is lost in the overall error/noise process of BR shooting?
