Variation of +/- .5 grains is huge for say a 270 Winchester or 30-06 sized cartridge. Percentage of difference would be roughly doubled in the 6mm ARC size cartridge. Only good part of this is the 6mm arc is targeting a relatively moderate pressure that may allow a bit of forgiveness.
My hair would start standing up w extreme nervousness if I was seeing a variation =/- .2 grains in a 6mm arc case four tenths total variation is a lot more than I feel may be deemed acceptable.
