When I first got my Load Master I was terrified of double charging a case. I bought the basic no frills press and was charging cases using a dipper. I took a 45-70 neck expanding die I was not using, dropped a 1/4" x 3" bolt into the die with a 5?16" washer to keep the bolt from falling through put it in the station after the charging station and had a redneck powder check. Didn't take long to add the Lee Auto Drum but continued to use my homemade powder check. I weigh either every 5th or tenth case depending on the powder have have found the Auto Drum to be very reliable,it throws fine grain powders like Tite Group within +/- .1 grain all day and flaky stuff like Unique and Red Dot within .2 grains all day. I've watched this for two years now, but just can't bring myself to set the powder check aside even though I'm confident that the operation of the machine and the measure will throw good charges and move the charged case away from the charging station, it is a very simple matter to screw the order of events up by pulling a case for some reason or other and returning it out of order. (My powder check caught a case I had weighed the set in the resizing station as I was talking with my wife. As I prime off press I have removed the decapping pin on all my pistol dies so it is possible to run a charged case through the resizing die and not know it doing things as I do, set up as I am) I know that the Lee 1000 doesn't have a station that could be used for powder check and I'm sure that other makers offer power check only as a kind of second thought, (Hornady offers a die they call the Powder Cop) So I'm curious, how do you guys that don't have or use a power checking station insure against the bad things that can happen?
