South Bend, Indianna have used Corbons 135 gr jhp @ 1325fps with dramatic effects. Now lets pump up that muzzle velocity

Does the Underwood ammo meet the "FBI" test criteria without raising problems in real world shootability in difficult circumstances or affecting the reliability of the current handguns?
