Mold 452-252-SWC for Reloading and Casting Bullets

LEE 2-cavity bullet mold designed specifically for .45 ACP, .45 Auto Rim, and .45 Colt (Long Colt) calibers, offering precision casting for metallic and semi-metallic reloading applications.

This mold produces .452 inch diameter, 252-grain Semi-Wadcutter (SWC) bullets, optimized for consistent performance and accuracy in handgun cartridges such as .45 ACP, .45 Auto Rim, and .45 Colt (Long Colt).

Featuring a ballistic coefficient of .136, these bullets provide reliable external ballistics suitable for target shooting, self-defense, and competitive handgun disciplines.

LEE’s 2-cavity molds represent an excellent balance between quality and affordability, making them a preferred choice among precision reloaders and ballistic enthusiasts seeking durable and efficient bullet casting solutions.

Constructed from corrosion-resistant aluminum blocks, these molds offer superior thermal conductivity compared to traditional iron or steel molds, allowing for faster heating and cooling cycles during the casting process, which enhances production efficiency.

The aluminum construction also reduces the overall weight by approximately one-third compared to iron or steel molds, minimizing operator fatigue during extended casting sessions and improving handling ergonomics.

The two halves of the mold are securely clamped together using robust tongs with wooden handles, ensuring zero movement or misalignment during the molten lead pouring phase, which is critical for producing uniform, high-quality bullets.

Note that the indicated bullet weights may vary slightly depending on the specific lead alloy composition used, as different alloys affect density and casting characteristics.

Included with the mold are the specialized tongs featuring ergonomic wooden grips for safe and comfortable handling of the hot mold during casting operations.

The mold is equipped with an integrated sprue cutter blade that functions as a lead pour gate, facilitating clean separation of the finished projectiles from the sprue, thereby reducing post-casting cleanup time.

For optimal mold longevity and bullet quality, it is highly recommended to thoroughly degrease the mold prior to initial use, followed by seasoning or applying a mold release agent specifically formulated for bullet molds to prevent lead adhesion and ensure smooth bullet release.

Under no circumstances should the interior cavity of the mold be lubricated, as this can degrade bullet surface finish and cause casting defects.

Lightly lubricate the sprue cutter retaining screw to maintain smooth operation and prevent corrosion, ensuring consistent sprue trimming performance throughout the mold’s service life.
