I may have spelled it wrong, but I think it was a guy on the castboolit forum with that handle name that came up with it. The idea was to take a piece of metal duct tape and put a piece inside the mold on either side of the cavity to shim it open a bit. That would give you a bit more diameter and sizing would straighten the boolit out and be slightly larger.

No sir I have not. I catch sales at the usual
Peddlers and/or on gun broker or Ebay. It
seems there are always folks trying to get
rid of stuff for cheap if you wait and look.

The new lee sizing die setup was designed for the new APP press. It has case/ bullet feeders that greatly speeds up brass sizing, boolit sizing and primer pocket swaging. I really like it. The new sizing dies do work on other presses and u can use the old sizing dies on the APP, but not as convenient.

in my paper work for the challenger press that came today, it appears that it can be used on any lee press

Yes, that is what I said, just not so concisely. And lots of other brand presses also.
