Considerations & Trade-offs

  • Best suited to handgun case reloading; using it for rifle cases requires the Double Disk Kit, so that setup adds an extra step and accessory requirement.
  • Charge selection is limited to the included disk options, so dialing in a specific volume depends on which disk combination fits your load.
  • It is designed for use with Lee reloading presses and Lee Powder Thru Expanding Die or Charging Die, which narrows compatibility outside that system.
  • The hopper holds 1/2 pound of powder, so larger-volume sessions may require refilling during extended use.
