  • 460 Rowland HK Mark 23

    This Beast has Shot 460 Rowland loads with no modifications to the gun and only the addition of a muzzle break.
    Our Max Load with a 185 gr bullet and 12.8 gr of Power pistol: From a 5" barrel velocity would be 1489 fps and energy 911 ft lb.
    Out of a Mark 23 barrel should be a little more.

    Be a good side arm for Grizz country...
    The deadliest weapon in the world is a Marine and his/her rifle.
