248Shooter turned me on to an offering from Detroit Bullet Works, a Michgan-based ammunition manufacturer. Touted as the “ultimate storage” system for your rounds, the Ammo Luggage systems are Pelican cases that are custom-cut to store and transport ammunition and impervious to most conditions shooters would encounter:
Each one stored securely, and safe from just about whatever mother nature can throw at it! Rain, sleet, snow, mud, even coffee, food and well just about anything except hot lava and fire will be kept out of your Ammo Luggage!
Ammo Luggage is currently available for 9mm (20 & 50 round counts available) and .308 (50 rounds only). The 9mm cases are available for $29.99 and $34.99 for the 20 and 50 round versions, respectively. The .308 commands a premium at $59.99.
