Will my .300 WSM cartridges fit properly in the MTM RMLD-50-16T ammo box?

Yes, this box is specifically designed for short-action magnums and heavy straight-wall cartridges up to a maximum overall length of 3.08 inches. This includes popular Australian hunting and target calibres such as .300 WSM, 6.5 PRC, and .45-70 Government. However, standard smaller calibres like .308 Win will fit too loosely and are better suited to the RS-50 or RL-50 models.

How does the clear green lid perform in low-light conditions out in the bush?

The translucent clear green lid allows you to quickly identify your ammunition loadout at a glance without needing to unlatch and open the box during early morning hunts or fading evening light. Combined with the included adhesive load data label, it helps you easily verify your reloading specs and sight-in notes in the field.

Is this MTM ammo box compliant with Australian firearm storage regulations?

As a passive polymer storage container, it contains no electronic components and therefore requires no electrical certifications like SAA or RCM. It complies with state and territory firearm storage standards when utilized as a secondary locked cartridge container stored inside an approved ammunition safe.

How durable is the hinge mechanism for long-term transport to the shooting range?

The RMLD-50-16T features a heavy-duty, full-length integrated mechanical hinge backed by MTM's 25-year manufacturer guarantee. The rugged polypropylene construction resists cracking and warping in harsh outback heat, while the positive Snap-Lock latch prevents accidental spills during transport in your vehicle or range bag.

The MTM Case-Gard RMLD-50-16T is a 50-round flip-top rifle ammunition box engineered for short-action magnums, heavy straight-wall cartridges, and medium large-diameter rifle cases.

Who is the MTM 50-Round Flip-Top Rifle Ammo Box for?

Reloaders loading short-action magnums and heavy straight-wall rounds — Organises batches on the bench with individual slots accommodating wide-diameter cases up to a maximum overall length of 3.08 inches (78.23 mm).
Hunters and target shooters — Secures a full 50-round supply of magnum ammunition for range transport or field hunting using a mechanical hinge and Snap-Lock latch.

Less suitable for: Cartridges exceeding 3.08 inches (78.23 mm) Max OAL (such as .300 Win Mag or 7mm Rem Mag), which require larger long-magnum ammo boxes, or standard-diameter short-action cartridges like .308 Winchester and 6.5 Creedmoor, which require smaller-diameter standard rifle ammo cases to prevent loose fitment.
