Lee 452-252-SWC Double Cavity

Recommended use

Designed for the production of .452" (252 gr) Semi-Wadcutter projectiles for reloading in .45 ACP, .45 Auto Rim and .45 Colt. This double cavity mold allows for increased output when manufacturing small batches for testing or range practice.

Design and operation

The mold has two identical cavities, allowing for the casting of two projectiles per cycle. The included handles facilitate opening/closing and handling during casting. Strict safety procedures must be followed when melting and casting lead alloys.

Dimensions and adjustments

The important dimensions influencing reloading are the .452" diameter , the 252-grain weight , the .665" OAL , and the distance from the crimp groove to the nose (.305"). These measurements allow you to anticipate case positioning and crimping; always check the mechanical fit with your cases and firearm before use.

Compatibility and practical advice

Compatible with the following calibers: .45 ACP, .45 Auto Rim, and .45 Colt, subject to dimensional control of your components. Use an alloy and pouring temperature appropriate for the mold (common lead-tin or lead-antimony alloys) and apply a release agent if recommended by the manufacturer. Check dimensions after cooling and deburr/remove any excess material if necessary.

• Production: 2 balls per cycle
• Quality control: measure diameter and OAL before reloading
• Safety: Wear protective gear, handle molten alloys with care

FAQ

• Q: Does this mold produce bullets suitable for .45 ACP?
  Yes, the .452" geometry and 252 gr weight correspond to profiles used in .45 ACP, .45 Auto Rim and .45 Colt — check the fit with your cases before use.
• Q: How many balls can be sunk per cycle?
  Two projectiles (double cavity).
• Q: Does the mold require specific handles?
  Handles are included with the mold; use heat-resistant gloves and follow safety instructions when pouring.
