I am using a Target Master trickler and RCBS scales and also have a MTM mini electronic scales. It still proves to be difficult to get consistent accuracy better than .3 grn. Calibrating the mini is reasonably straight forward but if the loads weighed out by the trickler and the RCBS are checked on the mini they vary. Now this could be as it seems and the RCBS are being slightly inconsistent or as I seem to want to believe it is the mini not holding its calibration very well.
Does anyone have any advice or thoughts how to weigh more accurately.
