Lee Semi-Wadcutter Pistol Mould (Handles Sold Separately) - 6 Cavity .358" 158 gr

The Lee Semi-Wadcutter Pistol Mould is a 6-cavity bullet casting mould designed for handloaders who want to cast consistent .358" semi-wadcutter projectiles at 158 grains. Built from aluminum rather than steel, this mould balances durability with practical advantages: it's lighter to work with during extended casting sessions, heats and cools quickly for efficient casting cycles, and resists rust—important in a reloading workshop. The CNC-machined block halves ensure each cavity produces bullets with tight dimensional consistency, and the hard anodized sprue plate with cam control lets you manage sprue separation cleanly. If you're casting volume for pistol loads, this six-cavity design speeds up production compared to smaller moulds.

Lee moulds are a go-to choice for serious reloaders who prioritize repeatability and value. The aluminum construction keeps fatigue manageable during long casting sessions—a real consideration if you're pouring hundreds of bullets at a time. The semi-wadcutter profile is popular for target shooting, training, and some hunting applications where controlled expansion and reliable feeding matter.

Note that handles are sold separately, so you'll need to pair this mould with a compatible Lee mould handle (or Lee casting ladle and handles kit) to get casting. Once set up, you'll have a workhorse tool that produces predictable, quality bullets for your .358" pistol loads.

Frequently Asked Questions

Do I need to buy handles separately for this mould?

Yes, handles are sold separately. You'll need to purchase a compatible Lee mould handle or a Lee casting kit that includes handles and a ladle.

What calibers can I cast with this mould?

This mould is designed for .358" diameter bullets at 158 grains—suitable for cartridges like .38 Special, .357 Magnum, and similar pistol loads that use that bullet diameter and weight.

Why aluminum instead of steel for a bullet mould?

Aluminum is lighter, reducing fatigue during long casting sessions, heats and cools faster for quicker casting cycles, and resists rust. Lee's CNC machining ensures the aluminum cavities produce consistent bullets despite the softer material.

Is this mould good for high-volume casting?

Yes. The 6-cavity configuration is designed for efficient volume production. Combined with the fast heat cycling of aluminum, it's well-suited to reloaders casting significant quantities of pistol bullets.
