Just curious if anyone has checked the accuracy of their calibration weight? While I check the calibration regularly, last night was the first time I actually weighed the weight. Mine reads between 50.02 - 50.04 on AC power, no fan or A/C running and inside the home. I called Dillon and was told that is not a problem and basically in spec. Unfortunately I do not have any match weight tips to check it against. I did check a few PD 115gr tips and they varied as well 115.02 - 115.04. I'm assuming this is not an issue that I should be concerned about since in the end my loaded charge will be .02 - .04 light. I'm loading near the upper end of the load range.
