Description

Storage for 10 rounds of 308 or similar cartridges with magnetic closure. The Slot in the front allows you to make labels for your custom loads or tear off the end of a box from factory ammo an insert it. Bullets are oriented down with a shelf that holds the neck to prevent any tip deformation. Magnets are 5/16 which may be sources from Harbor Freight or Amazon easily. As always use at your own risk, no warranty implied, and I ain't taking responsibility for nothing but the glory. Larger versions may be found in our Etsy store.
