These deluxe 50 round capacity boxes were 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. These 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. The H-50-XL is for the extra large hunting rounds. The calibers listed are for bullet up position; however some of the rimmed cases will fit better bullet down (thus use one or two sizes smaller). See bullet chart for your caliber.
