The R-100 Deluxe ammo box provides excellent protection for your reloads. It is made from virtually indestructible polypropylene with a handle for easy transportation. When the rounds are in the down position, they are protected by four special fingers, which keep your bullets from hitting the bottom of the box and causing tip damage. It comes with adjustable inner trays which offer two height positions. By rotating the tray, two height positions can be achieved in the box to accommodate different cartridge lengths.
