The Lee Precision Breech Lock 3-Die Set for .40 S&W (brand part no. 91880) includes colored Smart Lock bushings for quick die identification, a carbide full-length sizing die, a bullet seating die, a powder-through expanding die, a universal shell holder, a powder dipper, and printed instructions with load data. Lee notes this set can also load 10mm Auto by backing the bullet seating die and powder-through expanding die out roughly 1 3/4 turns, using 10mm load data found in Lee’s Modern Reloading manual; it can likewise load .41 Action Express by backing those same dies out about two turns, though load data for that cartridge must come from a powder manufacturer since Lee does not include it. Lee specifically warns against using reloads made with this set in Glock or similar pistols whose chambers do not fully support the cartridge at the feed ramp.
