Another vote for the RCBS Competition Measure. If you mount it on RCBS' stand, you can load 50 cases by just moving the loading block from case to case under the measure.

That said, I think the Dillon measures might be better because when I went from loading my handgun ammo on my Rock Chucker Supreme and the RCBS powder measure o a Dillon 650 and their measures, my 25-yard groups from a bench shrunk a little.
