Lee 2-Cavity Bullet Mold C501-440-RF 500 S&W Magnum (501 Diameter) 440 Grain Flat Nose Gas Check

The Lee 2-Cavity Bullet Mold C501-440-RF is built for handloaders casting heavy magnum revolver rounds. This aluminum mold produces .501-diameter, 440-grain flat-nose bullets with gas checks—the kind of hard-hitting projectiles that serious 500 S&W Magnum reloaders need. Lee's two-cavity design means you can cast pairs of bullets per cycle, speeding up production without sacrificing consistency or quality. The mold ships with handles included, so you're ready to start casting out of the box.

Aluminum construction is the backbone of Lee's molding philosophy. The material heats and cools faster than iron or steel, which reduces fatigue during long casting sessions and lets you work more efficiently. The blocks are rust-resistant, holding up to the demands of a serious reloading bench. The crimped block halves are precision-fitted to ensure bullets come out round and to spec, casting after casting—a real advantage when you're trying to maintain consistency across a batch of ammunition.

If you're a 500 S&W Magnum handloader who values repeatability and wants to move away from commercial cast bullets, this mold rewards the effort. The flat-nose profile and gas-check design are engineered for hunting and range work where bullet weight and expansion matter. Pair this with a reliable casting setup and you've got the foundation for custom, hard-hitting rounds tailored to your rifle or revolver.
