The Lee Pro 4-20 is a high-capacity bullet casting pot built for serious handloaders who cast their own projectiles in volume. This 220V melter holds approximately 20 pounds of lead, giving you the capacity to cast a full session without frequent refills. The generous 3¾-inch clearance under the spout accommodates standard bullet molds and most sinker molds, and the included adjustable mold guide lets you position any mold quickly and accurately for consistent pours.
The Pro 4-20's second-generation design combines Lee's patented high-efficiency heating with a dependable remote-sensing thermostat housed in a dust-tight enclosure. The 700-watt tubular heating element melts lead fast and recovers quickly between pours. Temperature control ranges from 450 to 900 degrees Fahrenheit, giving you the flexibility to find the sweet spot for your specific bullets—650 degrees is a solid starting point for most casting work.
Practical features make casting sessions smoother: a micro-adjustable flow control valve that adjusts with a screwdriver twist, and a front-mounted, replaceable valve spout that reseats instantly without tools. Low-maintenance design means less downtime and more time at the mold.
