What is the maximum cartridge overall length supported by the MTM RS-100-24?

The RS-100-24 has a strict maximum internal clearance threshold of 2.65 inches (67.3 mm). Cartridges exceeding this overall length, such as .243 Winchester or .308 Winchester, will not fit and require larger series boxes like the MTM RM-100.

Will this ammo box withstand harsh outback heat and rough field transport conditions?

Constructed from high-impact polypropylene, the box resists scuffing, warping, and oil degradation in typical outdoor environments. However, while it handles range transport and general bush use well, it is not O-ring sealed; for prolonged wet weather or harsh field conditions, a dedicated utility can is better suited.

Does this MTM ammo box comply with Australian firearm and ammunition storage regulations?

As a purely mechanical moulded plastic storage box with a Snap-Lok latch, it does not require electrical SAA/RCM certification. However, it is not an independently key-lockable safe, so it must be stored inside a locked container or safe to meet Australian state and territory firearm storage laws.

What calibre rounds fit into the individual compartments of this 100-round clear blue box?

The RS-100-24 is specifically tailored for small rifle calibres including .223 Remington, 5.56x45 NATO, .204 Ruger, .300 AAC Blackout, and .350 Legend. It holds exactly 100 rounds in individual slots, and the translucent blue finish allows you to check your round count and primer orientation instantly without opening the lid.

100 Round Ammo Box - MTM Case-Gard RS-100-24

Manufactured in the USA from high-impact polypropylene, it resists scuffing, chipping, warping, and chemical exposure from gun oils.

Who is the MTM 100-Round Flip-Top Rifle Ammo Box for?

Varmint Hunters — Requires a compact 0.69 lbs carry weight and 100-round capacity to transport high volumes of .223 Remington or .204 Ruger ammunition across field sessions.
Precision Reloaders — Needs individual grid compartments with a 2.65-inch maximum overall length clearance to batch-organise and label customised .300 AAC Blackout or .223 handloads.
Benchrest and Target Competitors — Relies on a 100-round rifle ammo box format measuring 4.8 inches by 5.2 inches to keep match-grade cartridges organised upright on competitive shooting benches.

Less suitable for: Cartridges exceeding the 2.65-inch (67.3 mm) maximum overall length threshold (such as .308 Winchester or 6.5 Creedmoor), which require a larger medium-to-large rifle ammo box, or extreme wet-weather field transport where a gasketed, O-ring sealed utility ammo can is better suited.
