The Lyman Mag 25 Digital Melting Furnace is a high-capacity digital bullet casting pot engineered for precision projectile manufacturing. Equipped with an 850 W heating element and an advanced PID digital thermal management system, the furnace maintains strict lead alloy temperature consistency. Its 25 lbs (approximately 11.34 kg) molten alloy capacity and bottom-pour valve mechanism allow reloaders to execute prolonged, uninterrupted casting sessions with uniform flow rates.

Key Features

  • PID Digital Thermal Control: Features a keypad interface with dual digital displays that show the target setpoint and the actual molten alloy bath temperature in real-time, holding setpoints up to approximately 850°F to 900°F (370°C to 455°C).
  • High-Capacity Melting Pot: The 4.4-inch (11.2 cm) diameter pot holds up to 25 lbs of casting alloy to support continuous, large-batch bullet production.
  • Bottom-Pour Dispensing: Includes an adjustable flow screw valve assembly to regulate stream velocity across various mould types.
  • Universal Mould Guide: Built with a 1 3/8-inch wide aluminum guide channel and 3.0 inches (76.2 mm) of spout-to-base clearance, supporting most standard 1-to-4 cavity moulds from Lyman, RCBS, and Redding/Saeco.
  • Integrated Workstation Utilities: Built-in mould warming shelf on top allows operators to preheat mould blocks prior to casting, alongside an integrated tool storage compartment.

Who is the Lyman Mag 25 Digital Melting Furnace for?

  • High-volume reloaders casting rifle and pistol bullets — 25 lbs molten lead capacity paired with an 850 W heating element provides the volume and continuous thermal recovery necessary for long bullet casting runs without frequent alloy replenishments.
  • Competitive shooters demanding strict alloy consistency — PID digital temperature management system monitors the 4.4-inch diameter alloy bath in real time to eliminate temperature swings between cast projectiles, ensuring shot-to-shot weight uniformity.

Less suitable for: Small-batch casting runs requiring under 10 lbs of alloy, where compact 4–10 lb production pots offer faster setup and lower power draw; commercial multi-operator operations requiring dedicated industrial foundry furnaces exceeding 50 lbs; wide hollow-point moulds or standard 6-cavity blocks requiring clearance beyond the 1 3/8-inch mould guide channel; and high-temperature metal casting involving brass, bronze, cast iron, or pure aluminium exceeding standard alloy temperatures.
