The Underwood 10mm Auto 150gr Xtreme Hunter comes as 20 rounds loaded with a lead-free solid copper bullet (Underwood part no. 900). Underwood built the Xtreme Hunter line from its Xtreme Defender design, keeping the optimized nose flute and tuning weight and velocity for maximum penetration depth. The maker says the solid copper body keeps thick hide, bone and other barriers from having much effect on the permanent wound channel. Cases are nickel-plated brass, and the powder is flash suppressed so low-light shooting does not wreck your night vision. It is a 10mm load for woods carry and hunting handguns where penetration matters more than expansion.
