Lee Semi-Wadcutter Pistol Mould - Double Cavity (Handles Included) .358" 158 gr

The Lee Semi-Wadcutter Pistol Mould in .358" 158-grain is purpose-built for handloaders who cast their own bullets. This double-cavity mould lets you produce two bullets per pour, speeding up your casting workflow without sacrificing consistency. Semi-wadcutter profiles are favored for pistol loads that demand reliable feeding, straight-wall penetration, and a clean wound channel—ideal for target work, defense loads, and hunting applications where bullet design matters.

Lee's casting moulds are machined from aluminum, a choice that offers real advantages for the bench reloader. Aluminum won't rust, it's significantly lighter than steel or iron (reducing hand and arm fatigue during long casting sessions), and it cycles through heat and cooling faster, which means less waiting between pours. The tradeoff is that aluminum is softer than blued steel, so these moulds reward careful handling; treated gently, they'll provide years of reliable service and thousands of castings.

The mould ships with steel handles permanently attached, giving you a secure grip during the pour and easy ejection of finished bullets. Everything you need to start casting is in the box—just connect it to your lead pot and begin producing ammunition tailored to your loads and your gun.

Frequently Asked Questions

What calibers and weights does Lee offer in the semi-wadcutter mould line?

Lee produces semi-wadcutter moulds in a range of weights, including 90, 140, 158, 195, 214, and 240 grains, in various calibers. The .358" 158-grain is one of the most popular configurations, especially for mid-range pistol loads.

Will an aluminum mould work as well as a steel one?

Yes, aluminum moulds perform excellently and offer some advantages: they resist rust, cool and heat faster for quicker casting cycles, and are lighter to handle. The tradeoff is that aluminum is softer than blued steel, so they require gentle handling to maintain accuracy over thousands of castings.

Does the mould come with handles?

Yes, this mould includes steel handles that are permanently attached. No additional equipment is needed to start casting.

What does semi-wadcutter mean for my loads?

A semi-wadcutter bullet features a shallow cone point over a cylindrical body, combining reliable feeding in semi-automatic and revolver chambers with a wider wound profile than a round-nose bullet. It's a versatile choice for target shooting, hunting, and defensive loads.
