The Lehigh Defense 10mm Auto 190-grain Wide Flat Nose bullets (brand part no. 04400190SP) are .400-diameter solid copper projectiles for reloaders. Lehigh Defense builds its Wide Flat Nose line to deliver deep, straight-line penetration, and this .400 size is the one Lehigh calls optimal for 10mm Auto handgun and .400 Legend rifle loads. The bullets are projectiles only, sold as 50 to the box, and are not loaded ammunition. A strategically designed meplat helps with penetration and feeding, and relief bands help preserve velocity. For hunters loading 10mm for big, tough game, it is a purpose-built option.

Key Specifications

• The bullet diameter is .400 inch, the size for 10mm Auto handgun loads and .400 Legend rifle loads.
• Bullet weight is 190 grains, a heavier 10mm weight suited to deep penetration.
• The design is a Wide Flat Nose, a proven shape for deep and straight penetration on game.
• The bullet is solid copper, which Lehigh says has a tensile strength 10 to 20 times greater than conventional lead projectiles.
• Because of that strength, the bullet resists deformation against heavy bone, which nearly eliminates deflection from a deformed projectile.
• The meplat is designed for deep penetration and proper feeding in semi-auto firearms.
• Relief bands on the bearing surface are designed to maximize the cartridge’s velocity potential.
• Each box holds 50 bullets, which is enough for a solid working load development session.
• Solid copper construction meets lead-free projectile rules in states and jurisdictions that call for lead-free bullets, and these are components only, not loaded ammunition.
