LEE Undersize Sizing Die

Lee Undersized Carbide Sizing Die – .003 in smaller than Lee’s standard carbide die, so bulged brass (the “Glock bulge”) is sized fully for tight match chambers. Choose 9mm Luger (90313) or 38 Super (90333). Sizing die only; no licence required.

$89.95

The Lee Undersized Carbide Sizing Die is a full-length carbide pistol sizing die made .003 in smaller than Lee’s standard carbide die. Brass fired in generous or unsupported chambers often keeps a bulge near the web that a normal die leaves behind, and that bulge is what causes feeding and chambering problems in tight-chambered competition pistols. Running cases through the undersize die restores them to a diameter that chambers freely. We stock the 9mm Luger die (Lee part 90313) and the 38 Super die (part 90333); both are the sizing die only, with a standard 7/8-14 thread for common single-stage, turret and progressive presses.

Key features

  • Carbide sizing ring – no case lube needed for straight-wall pistol brass
  • .003 in under Lee’s standard carbide sizing diameter
  • Removes the bulge left by unsupported chambers
  • 9mm Luger = Lee 90313; 38 Super = Lee 90333
  • Standard 7/8-14 die thread
  • Sizing/decapping die only – pair with your existing expander and seating dies

Frequently asked questions

Will it over-work my brass?
It sizes only .003 in tighter than standard; Lee sells it for exactly this use. Normal case life applies, though heavily bulged cases should be inspected.

Is it a full die set?
No. You receive the undersize sizing die only; keep using your current expander, seater and crimp dies.

Does it need a licence?
No. Reloading dies are not firearms or ammunition; this item ships Australia-wide.

Shooting accessory – not a firearm or ammunition; no licence is required to purchase and it ships Australia-wide. Specifications from the manufacturer. 3 Gun Tactical, Licensed Firearms Dealer 50001578, Tingalpa QLD.
