Lee powder measures use a charging die to accuate the powder measure. As the case goes into the die it contacts the hollow expander which pushes up on the powder measure causing the disk to slide foreword dropping the powder charge through the hollow expander into the case. The expander bells the case mouth at the same time. The amount of case mouth belling is adjusted by screwing the die body in and out of the turret.
The charging dies are caliber specific for pistol cartridges but only one is made for rifle cartridges as it doesn't bell the case mouth when the powder is dropped into the case.
The Pro 1000 will load all pistol cartridges but only rifle cartridges that are the length of 5.56x45mm/223 Remington or shorter.
If you don't have a copy of the instructions for the press or powder measure download and print them out from

You will need them as you will have to refer back to them when you have problems.
I own two Pro 1000's and a Loadmaster. I bought my first Pro 1000 in the late 1980's so trust me I know Lee progressive presses.
The first thing you need to do is get a spray can of brake parts cleaner,100% alcohol,or laquer thinner. Q-tips,cleaning patches,and a bottle of Loc-eze(liquid graphite used to lube locks) or spray can of graphite. I have found that brake parts cleaner is best to use as it is easy to flush the primer system parts of any fibers left from the Q-tips or cleaning patches off with it.
Take the shell plate carrier apart and clean all oil/grease off of every part. Remove the primer feeder and priming parts. Clean them with brake parts cleaner. Pull the trough that the primers slide down from the primer tray into the carrier apart it is two pieces. Use brake parts cleaner and Q-tips to clean inside it.
Lube the moving parts of carrier and press with a light coat of graphite a thick application and small chucks of graphite will work their way into the primer feeder which is real bad.
As long as the primer feeder is kept clean it will function 100%.
