Lee Semi-Wadcutter Pistol Mould - Double Cavity (Handles Included) .358" 150 gr

If you're casting your own pistol bullets, a Lee Semi-Wadcutter Pistol Mould in .358" 150 gr is a core tool for consistent, repeatable results. This double-cavity mould lets you produce two bullets per cycle, speeding up your casting workflow without sacrificing quality. The mould comes complete with handles, so you're ready to start casting straight out of the box—no additional purchases needed to get going.

Lee built this mould from aluminum, a choice that matters for the person spending hours at the casting pot. Aluminum heats and cools faster than iron or steel, which means less thermal shock to the blocks and easier handling during long casting sessions. The lighter weight reduces hand and arm fatigue, a real benefit when you're committed to producing volume. The specially crimped block halves are engineered to hold tolerances—you'll get properly rounded, correctly sized bullets even after hundreds of casts.

Semi-wadcutter bullets are popular in handloading circles for target shooting and practice where their flat nose provides a clean hole in paper, and they're also carried by reloaders who shoot a variety of pistol disciplines. Whether you're loading for .38 Special, 10mm, or other cartridges that use .358" projectiles, this mould gives you control over your ammunition and the satisfaction of shooting rounds you cast yourself.

Frequently Asked Questions

What cartridges can I load with .358" 150 gr semi-wadcutter bullets?

This mould produces .358" diameter projectiles suitable for cartridges that accept that bore diameter. Common applications include .38 Special, 10mm, and other pistol rounds in that family. Always consult your reloading manual to confirm bullet weight and type are appropriate for your specific cartridge and firearm.

Do I need to buy handles separately, or are they included?

Handles are included with this mould, so you have everything needed to start casting immediately.

Why choose aluminum over iron for a bullet mould?

Aluminum heats and cools faster than iron or steel, which reduces thermal cycling stress on the mould and makes it easier to handle during extended casting sessions. The lighter weight also cuts down on hand and arm fatigue, a meaningful advantage if you're casting in volume.

How many bullets does the double-cavity mould produce per casting cycle?

This is a double-cavity mould, meaning each cycle produces two finished bullets, helping you cast more efficiently than a single-cavity design.
