Product Description Designed at the request of the growing number of 50 BMG users. They told us they only needed 10 rounds and they preferred a slip top design. We added bullet tip protection for most bullets seated at standard lengths. This is done by holding the rounds at the shoulder. For 50 BMG, 50 DTC, 460 Steyr, HS 460, 416 Barrett. MTM is a family owned and operated, plastic injection molding facility with a primary focus on the shooting sports. First opening it's doors in 1968, MTM Molded Products began as a simple idea for storing ammo. Founder, Bill Minneman, an avid hunter since early childhood, needed a sturdy container to store his reloaded ammo. At the time, everyone settled with paper bags or cardboard boxes. A toolmaker by trade, and a practical inventor by nature, Bill created the Case-Gard 50 series, which is still available today. From ammo boxes to gun rests to clay target throwers, MTM offers a huge variety of products all specifically designed for the shooting sportsman.
