As mentioned there is no single perfect measure. Learning to get the best from what you have helps. In my case getting the best demands a lot of practice and attention. I have a Harrell's, both Hornady in a progressive and RCBS with micrometer inserts and baffles but for log/stick IMR powders I like a Quick Measure from JDS. There have been some strong recommendations for the Quick Measure posted on this board but the strongest advocates have left the range.
