About This Underwood Maximum Expansion 45 Colt Long Colt Load

Underwood loads this cartridge with the Lehigh Defense Maximum Expansion bullet, a solid copper projectile machined with deep internal cuts. Those cuts cause the bullet to peel open into several petals immediately on contact with soft tissue. Because the bullet is solid copper, it does not fragment or lose weight even as it expands dramatically. Liberty Anno Supply stocks this loading in 20-round boxes for shooters who want maximum immediate effect. This kind of consistency matters most when a hunt or a defensive situation is on the line.
