Mold 452-300-RF for Precision Reloading and Hunting Ammunition
LEE 2-Cavity Bullet Mold specifically engineered for .45 Colt (Long Colt) and .454 Casull calibers, designed to produce high-quality cast projectiles with precision and consistency.
This mold casts .452 diameter, 300-grain round flat nose (RF) bullets optimized for use in .45 Colt (Long Colt) and .454 Casull handloads, providing excellent ballistic performance and reliable terminal ballistics for hunting and target shooting applications.
Featuring a ballistic coefficient (BC) of approximately .233, these bullets offer a balanced trajectory and energy retention, making them ideal for medium to long-range shooting scenarios where accuracy and penetration are critical.
LEEs 2-cavity molds are highly regarded among metallic and semi-metallic reloaders seeking durable, cost-effective solutions without compromising on bullet uniformity and weight consistency. The dual cavities allow for increased production rates, enhancing efficiency during casting sessions.
Constructed from high-grade aluminum blocks, these molds exhibit superior corrosion resistance compared to traditional iron or steel molds, ensuring longevity and minimal maintenance in various environmental conditions.
Aluminum molds benefit from rapid thermal cycling; they heat up and cool down significantly faster than iron molds, reducing downtime between pours and improving overall casting throughput. Additionally, aluminums lightweight natureapproximately one-third lighter than iron or steel moldsreduces operator fatigue during extended bullet casting operations.
The mold halves are securely clamped together using robust wooden-handled tongs, ensuring precise alignment and preventing any movement during the molten lead pour. This tight seal guarantees consistent bullet dimensions and reduces the risk of casting defects such as flash or misruns.
Note that bullet weights may vary slightly depending on the specific lead alloy composition and casting temperature, so reloaders should verify weights to maintain load consistency and safety.
The included tongs feature ergonomic wooden grips for comfortable handling and enhanced control during the casting process.
An integrated sprue cutter blade is incorporated into the mold design, facilitating clean separation of the bullet from the lead sprue immediately after solidification, streamlining post-casting cleanup and preparation.
For optimal mold performance and bullet quality, it is strongly recommended to thoroughly degrease the mold before initial use. Additionally, seasoning the mold by applying a light coat of mold release agent or smoking the interior surfaces helps prevent lead adhesion and extends mold life.
Never lubricate the interior cavity of the mold, as this can negatively affect bullet surface finish and dimensional accuracy.
Lightly lubricate the sprue cutter pivot screw to maintain smooth operation and prevent corrosion, ensuring consistent sprue trimming throughout the molds service life.
