Lee 6-Cavity .358-inch 105gr Semi-Wadcutter Bullet Mould (.357 Magnum)

Lee Precision’s Lee 6-Cavity .358-inch 105gr Semi-Wadcutter Bullet Mould (.357 Magnum) (brand part no. 90315) is a 6-cavity aluminum mould designed to drop a .358-inch, 105-grain Semi-Wadcutter bullet for .357 Magnum handloads. It drops a .358-inch diameter, 105-grain semi-wadcutter cast bullet with a sharp shoulder ahead of a flat nose that punches a clean, easy-to-score hole in paper while still feeding reasonably well through most revolvers. It’s a straightforward, affordable way to cut per-round cost for anyone casting their own .357 Magnum bullets at volume.

Key Specifications

• Casts a .358-inch diameter bullet, sized for .357 Magnum.
• Bullet drops at a nominal 105 grains, worth confirming against your load data since cast bullet weight varies slightly with alloy.
• Bullet profile is Semi-Wadcutter, offering a sharp shoulder ahead of a flat nose that punches a clean, easy-to-score hole in paper while still feeding reasonably well through most revolvers.
• The mould is a 6-cavity block, so a single pour drops six bullets instead of one or two.
• The block halves are machined from aluminum instead of iron, shedding heat quickly between pours and resisting the rust that plagues steel moulds.
• CNC machining on the block halves keeps every cavity true to spec, which shows up as consistent bullet weight and diameter.
• The sprue plate is hard-anodized and cam-actuated, cutting the sprue cleanly while standing up to repeated use.
• Mould handles are not included and need to be purchased separately to run this block.
• Sized for .357 Magnum loads, matching the block’s .358-inch bullet diameter.
