I bought this to store rifle ammo and to transport rifle ammo to 3-gun matches. It's great. It will hold 200-300 rounds depending upon caliber (200 @ .308, 250 @ 6.8 SPC, 300 @ .223). The 2500 will hold 100 + .223 rounds. The OtterBox 2000 is good for 100 + 9mm pistol rounds. Air tight.
Pros: durability, see-through
Cons: none
