Overview

Built for organized rifle ammunition storage, this MTM CASE-GARD box is designed to hold 20 rounds in a bullet-up position for quick visual checks and orderly transport. Its polypropylene construction is described as virtually indestructible and resistant to warping, cracking, chipping, peeling, expansion, and contraction, making it a practical choice for range bags, loading benches, and field carry. The case is listed for a wide range of rifle cartridges, including several magnum and specialty chamberings, so it suits shooters who keep multiple loads or larger-format rounds on hand. The slip-top design keeps the profile simple, while the 3.84" lid height is noted for compatibility with the specified overall lengths.

Pros

Considerations & Trade-offs

  • This case is listed for a wide range of cartridges, so fit should be checked carefully against your specific load before purchase.
  • Rounds are stored bullet-up, which is useful for identification but may not match every shooter’s preferred orientation for transport or bench use.
  • The polypropylene construction is described as highly durable, but this is still a lightweight storage case rather than a hard-sided ammo box.
  • The product description gives lid OAL, but not full exterior dimensions, so space planning for packs, range bags, or storage requires verification.
