lee auto drum finger knob wrench

Hi there, I've got a great hack for you! To make the Lee Auto Drum Powder Measure easier to use, I recommend adding a finger wrench that fits snugly onto the nut. It's a game-changer when it comes to switching out drums quickly and easily. On my model, it fit perfectly right off the bat, but you might need to enlarge it by 1-2% for a looser fit.
