This Lee Precision double cavity combo mold is built for .50 caliber muzzleloader shooters who cast their own projectiles. One cavity produces a .490 diameter round ball weighing 177 grains, the other a 320 grain R.E.A.L. (Rifling Engraved At Loading) bullet. That pairing covers two distinct loads from a single tool, making it a practical choice for anyone running a patched round ball for general shooting and a heavier conical for hunting weight. The mold ships with handles and a sprue plate, so it works out of the box once you have a lead pot and pour spout ready.
The mold blocks are CNC machined from aluminum, which keeps them rust resistant and lets them heat up and cool down faster than iron or steel molds. In practice, that means good projectiles after only a few casts instead of a long warm-up. Trochoidal venting on both the mold face and the sprue plate helps air escape during the pour for cleaner fill-out and fewer voids. The .490 ball seats with a patch in standard .50 caliber bores, while the 320 grain R.E.A.L. design grips the rifling at loading for repeatable seating depth. Lee backs the mold with a two-year guarantee against defects in workmanship, and the unit is made in Hartford, Wisconsin. Pair it with the right bullet lubricant for the conical loads.
Black powder and muzzleloader shooters reach for a mold like this to keep round ball and conical costs down while casting in volume. Run the .490 round ball with patches for plinking and target work, then switch to the 320 grain R.E.A.L. for heavier hunting loads out of the same .50 bore. Aluminum construction makes it forgiving for casters still dialing in their pot temperature and pour rhythm. Browse the rest of our bullet casting equipment for handles, lead pots, and sizing gear, or check our measuring tools and calipers to verify finished diameters before loading.
It is a double cavity combo mold. One cavity casts a .490 diameter round ball weighing 177 grains, and the other casts a 320 grain R.E.A.L. conical bullet, both sized for .50 caliber muzzleloaders. The product title emphasizes the round ball and 320gr REAL, but you get both projectile types from this single tool.
Yes. Per Lee Precision specifications, this mold ships with handles and a sprue plate included, so you can begin casting once you have a lead melting pot and pour spout. No separate handle purchase is required for this particular combo unit.
Aluminum blocks are rust resistant and heat up and cool down faster than iron or steel molds. That faster thermal response means good projectiles can usually be produced after only a few casts, which shortens the warm-up time at the start of a casting session.
The .490 diameter round ball is intended for .50 caliber muzzleloading rifles and is loaded with a patch in standard .50 bores. Bore and patch combinations vary, so verify finished ball diameter and your preferred patch thickness against your specific rifle before loading.
