Lee Precision Mold 6 Cavity TL401-175-SWC

Six Cavity Commercial Quality Molds

Made for heavy duty volume production, this Lee Precision Six Cavity Bullet Mold produces .401 diameter, 175 grain Semi Wad Cutter nose bullets suitable for .40 S&W (Smith & Wesson), 10mm and similar cartridges. This mold, like all Lee Precision molds, is made from aluminum and so is completely rust resistant, lighter, and heats up and cools down faster than other brands made from iron or steel. As a result, this Lee mold is easier to use, causes less operator fatigue during casting and can produce more consistent bullets than other molds made from iron or steel. Lee's 6 cavity mold blocks are machined from aluminum and assembled with steel bushings and alignment pins for lasting precision.

A sprue plate is included but Handles are sold separately. The bullet weight specified is based on using Lee's suggested alloy, your results may vary depending on the actual alloy used.

Lead Information:

  • The following lead information is from the Lee Precision Modern Reloading 2nd Edition Book, Pages 119 & 120.
  • For best results, bullet strength must be matched to breech pressure.
  • Black Powder guns require Pure Lead.
  • Target handgun loads should use Lead with 1% Tin. Tin makes bullet alloy more castable & harder.
  • Lead with some wheel weights used for high pressure handguns.
  • Use Wheel Weights for very light rifle loads.
  • High Pressure Rifle loads use Linotype.
  • Beware of Zinc! One part Zinc in 10,000 parts of Lead Alloy will ruin it's castability.

WARNING: Melting lead and casting lead objects will expose you and others in the area to lead which is known to cause birth defects, other reproductive harm and cancer.


Lead contamination in the air, dust and on your skin is invisible. Keep Children and pregnant women away during use and until clean-up is complete. Risk can be reduced, BUT NOT eliminated , with strong ventilation. Washing hands immediately after use of these products before eating or smoking. Careful cleaning of surfaces and floors with disposable wipes, after lead dust has settled. Use lead-specific cleaner with EDTA or high phosphate detergent (such as dishwasher detergent). Bag wipes for disposal.



  • DO NOT USE more powder than recommended
  • DO NOT USE a heavier bullet than recommended
  • DO NOT SEAT the bullet deeper than normal
  • DO NOT USE magnum primers unless using a slow burning ball powder
  • Greatly oversize bullets, excessively hard bullets or cases that are too long will cause higher pressures
  • High temperatures or cartridges that were stored in a hot car or trunk will produce higher pressures
