The Lyman 4500 Lube Sizer with heater is a cast bullet lubrication and sizing tool built for reloaders who cast their own projectiles. If you're running a casting operation and need to size and lubricate bullets efficiently, this machine takes the friction and tedium out of the process. The integrated 115-volt heater speeds up the cycle, letting you work through batches faster than hand-sizing alone, and the ergonomic design won't leave your hands cramped at the end of the day.
This sizer uses hard lubricants (the kind that come in stick form), and Lyman includes one stick with the machine to get you started. The solid-bottom long handle gives you mechanical advantage for consistent pressure and smooth operation, while the built-in gas check seater handles primed bullets ready for the press. If you already own RCBS Lube-a-Matic 2 dies or top punches, they're cross-compatible with the 4500, so you won't need to buy a whole new set of tooling to make the switch.
Whether you're loading cast bullets for pistol or rifle, this is a straightforward, reliable way to prep them. The heater keeps the lube at the right consistency, and the ergonomic grip means you'll stay comfortable through long reloading sessions.

Yes, the 115-volt heater is built into this model and helps speed up the lubrication and sizing process by keeping the lubricant at the correct consistency.
