I have read so many times "send it back to lee and for a few dollars they will fix/tweek it".
If they made it right the first tme there would be no need for tweeking. The lee powder measure leaks powder, thats a fact.
RCBS, Lyman, Hornady, and Redding warrenties their products even if you did not buy them new.
Bought a used set of 8x57 dies, found the expnder ball missing---RCBS sent a new one no questions, it was in the mail three days later (no cost). Lyman and Hornady have done the same for me. Redding I have had no warrenty issues with.
