RCBS Powder Measure
As powder measures go I've only used 3 enough to comment. Over the last few days I've loaded 300 each .223 & 200 each 22-250 all with 4895. All charges were thrown from the RCBS & I found the measure very accurate. Variations were less than 1/2 a tenth of a grain [you do the math]. This measure cuts very few grains of powder but when I did cut a grain the powder charge was 'bout 4 tenths of a grain heavy every time. So long as the measure traveled smoothly through its cycle there was no reason to weigh.
