Lee 6-Cavity .401-inch 175gr Truncated Cone Bullet Mould (10mm Auto)

For handloaders casting their own 10mm Auto and .40 S&W bullets, the Lee 6-Cavity .401-inch 175gr Truncated Cone Bullet Mould (10mm Auto) (brand part no. 90690) from Lee Precision is a 6-cavity aluminum mould worth a look. It drops a .401-inch diameter, 175-grain truncated cone cast bullet with a flat-tipped conical ogive that aligns well in the case mouth, a shape favored for semi-auto pistol loads run on a progressive press. It’s a straightforward, affordable way to cut per-round cost for anyone casting their own 10mm Auto and .40 S&W bullets at volume.

Key Specifications

• Casts a .401-inch diameter bullet, sized for 10mm Auto and .40 S&W.
• Bullet drops at a nominal 175 grains, worth confirming against your load data since cast bullet weight varies slightly with alloy.
• Bullet profile is Truncated Cone, offering a flat-tipped conical ogive that aligns well in the case mouth, a shape favored for semi-auto pistol loads run on a progressive press.
• The mould is a 6-cavity block, so a single pour drops six bullets instead of one or two.
• Like the rest of Lee’s mould line, the blocks are cast from aluminum rather than steel, so they run noticeably cooler for the caster and won’t rust in storage.
• Both block halves are CNC-machined, so cavity dimensions stay consistent from one bullet to the next.
• A cam-operated, hard-anodized sprue plate cuts the sprue off cleanly rather than tearing or dragging lead across the bullet base.
• This block ships without handles; a set of standard bullet-mould handles is required and sold separately.
• Sized for 10mm Auto loads, matching the block’s .401-inch bullet diameter.
• Uses Lee’s tumble-lube band design, so cast bullets are lubed by tumbling in liquid Alox rather than run through a lubrisizer.

What cartridges is this bullet sized for? The .401-inch, 175-grain truncated cone bullet is intended for 10mm Auto and .40 S&W handloads.
