These sturdy ammo boxes are great for reloading or storing ammunition for any length of time. The boxes are clearly marked with the caliber and the translucent exterior lets you see inside so you know which boxes are full or just partially so. Snap lock lids and full length hinges keep ammo secure and in place. A much better alternative than using manufacturer's paper boxes for keeping your valuable ammunition protected from the elements. With a dozen different sizes and clearly marked calibers on the exterior, there is no guess-work on figuring out what size to use and whether the box will fit your rounds. Fits 100 rounds for the 6.5 x 284, .284/.308 Win, .284 Shehane, or .30-06.
