The Lee Round Ball Mould with handles is a practical choice for shooters who cast their own roundballs for muzzleloaders, historical firearms, or specialized loads. This double-cavity .433" mould produces balls weighing 121.87 grains—ideal for common percussion and flintlock applications where consistent projectile weight matters for accuracy and ballistic uniformity. Unlike buying pre-cast ammunition, owning your own mould means you control quality, cost, and supply on your own schedule.
Built from aluminum rather than steel or iron, this mould heats and cools faster, letting you maintain a steadier casting pace and get back to the range sooner. The material also resists rust, a real advantage in reloading benches where humidity and solvents are part of the job. The block halves are CNC-machined to tight tolerances, reducing the fatigue and wear that can creep into older casting equipment and keeping your roundballs smooth and consistent shot after shot.
The included handles are a welcome feature—many competing moulds sell handles separately. They're built to handle the thermal cycling of casting without loosening or warping, so you're not fumbling with your mould cavity between pours. Whether you're working up loads for a .45-caliber rifle, a .50-caliber smoothbore, or a period-correct revolver, this .433" double-cavity design lets you produce matched pairs of projectiles efficiently, keeping your casting sessions productive and your ammo costs down.
| Ball Diameter | .433" |
| Ball Weight | 121.87 grains |
| Cavities | 2 |
| Material | Aluminum |
| Handles Included | Yes |
The .433" ball is common for .45-caliber muzzleloaders, including rifles and smoothbores, as well as some period percussion revolvers. Check your bore diameter and historical loading data to confirm compatibility with your specific firearm.
No. This mould comes with handles included, so you can start casting right away without additional purchases.
Aluminum heats and cools more quickly than steel or iron, which helps you maintain consistent casting temperature and work faster. It also resists rust, reducing maintenance and extending the life of your equipment.
The double-cavity configuration allows you to cast two roundballs per pour, doubling your output compared to single-cavity moulds and keeping your loading sessions moving efficiently.
