I have been reloading for a long time, over 20 years. Have used a Lee "Perfect" powder measure for awhile now. It works pretty decent with powders such as IMR 3031 and 4064, but does not work worth a hoot with ball type powders, as the powder literally will pour out the side of the measure. I guess cheaper is not always better. Hate to spend what RCBS or Hornadys measures cost, but looks like I might have to.
