I'd say that is true of most of these volumetric powder measures. I just picked up an old Lyman 55. I believe it was made before they were bought out, since it is all orange, even the handle and the knocker. I am going dissemble and clean it up before trying it out, but it's in pretty good shape. It even has the metal hopper lid.I have an Ideal No 5 powder measure.They as accurate as any current non benchrest measure.Operation method is the only thing that can affect accuracy.
