I have the Hornady model. It works well for rifle charges. Smallest I do with it is .30 Carbine.
For pistol loads, especialy small volume cases like .45 auto, 9mm Luger, .40 S&W and such the standard powder measure, with a good metering powder will be worlds faster.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
