The Deluxe H-50 ammo box was designed for ultimate ammo protection and ease of transporting. Bullets are placed in the box in the down position and are protected by four special fingers. The fingers are designed to keep most bullet tips from hitting the bottom of the box preventing tip damage that can change bullet flight characteristics. There is also extra space provided between rounds to facilitate easy removal. The convenient fold down carrying handle is specifically designed so that belted magnum rounds can be carried rim up or down.
