Lee C501-350-RF Double Cavity Mold

The Lee C501-350-RF Double Cavity Mold is a precision reloading tool engineered for handloaders who require high-capacity, heavy-grain projectiles for magnum rifle and pistol cartridges. Designed for shooters working with the 500 S&W Magnum and 50 Beowulf platforms, this double-cavity configuration accelerates production without sacrificing consistency or accuracy. Whether you're a competitive shooter, law enforcement firearms instructor, or serious handloader, this mold delivers the repeatability needed for reliable ballistic performance downrange.

Manufactured by Lee Precision, a leader in reloading equipment since 1959, this double cavity mold produces .501-diameter bullets weighing 350 grains—the ideal weight for achieving proper velocity, energy retention, and terminal performance in large-bore magnum applications. The dual-cavity design cuts casting time in half compared to single-cavity molds, allowing experienced handloaders to produce consistent bullet weights and dimensions batch after batch. Hardened steel construction ensures durability across hundreds of casting cycles, while included handles provide safe, ergonomic operation at the casting bench. The precise cavity geometry guarantees bullets that chamber reliably and maintain tight shot grouping when loaded to proper specifications.

This mold is ideal for dedicated 500 S&W and 50 Beowulf shooters who demand uniformity in their hand-cast ammunition. Tactical shooters and law enforcement armorer communities benefit from the efficiency gains and cost savings of casting proprietary heavy projectiles in-house, particularly for specialized training protocols. Compatible with standard Lee Precision casting handles and furnace systems, the C501-350-RF integrates seamlessly into existing reloading setups. Proper alloy selection and casting temperature management will ensure optimal bullet quality and consistent ballistic performance across all loadings.
