The Lee Precision 90283 delivers consistent .530 diameter round balls for black powder enthusiasts and traditional muzzleloader shooters. This aluminum construction mold with hardwood handles produces two identical projectiles per casting cycle, maximizing efficiency during bullet preparation sessions.

What Makes This Different

Unlike single-cavity molds that slow down production, this double-cavity design cuts casting time in half while maintaining dimensional consistency across both cavities. The aluminum construction heats faster and more evenly than iron alternatives, reducing wait times between pours. Each cavity produces bullets within 0.001-inch tolerance when properly heated and maintained.

Key Features

  • Double cavity design produces two .530 diameter round balls per pour
  • Aluminum construction for rapid, even heating and consistent results
  • Hardwood handles provide secure grip and heat protection during use
  • Precision-machined cavities maintain tight dimensional tolerances
  • Compatible with standard lead melting furnaces and ladles
  • Sprue plate design ensures clean bullet separation
  • Compact size stores easily in reloading bench drawers
This mold performs reliably with pure lead or lead alloys up to 10:1 tin-to-lead ratios. The .530 diameter suits .54 caliber rifles including Thompson/Center Hawken, CVA Mountain Rifle, and similar traditional muzzleloaders. Proper mold temperature produces smooth, consistent bullets that seat uniformly with patching material for improved accuracy downrange.

Technical Specs

  • Bullet diameter: .530 inches
  • Cavity count: 2 bullets per casting cycle
  • Construction: Aluminum body with hardwood handles
  • Bullet weight: Approximately 230 grains with pure lead
  • Compatible calibers: .54 caliber muzzleloaders
  • Manufacturer: Lee Precision, USA
  • Model number: 90283
This mold represents proven Lee Precision engineering at an accessible price point. The double-cavity efficiency reduces casting sessions while aluminum construction ensures decades of reliable service with proper care.
