MTM Case-Gard RS-100-24 100 Round Rifle Ammunition Box

The MTM Case-Gard RS-100-24 100 Round Rifle Ammo Box has been a trusted choice of rifle shooters and reloaders since 1968. Designed to provide compact, secure ammunition storage, it is ideal for competitive shooters, varmint hunters and precision reloaders who need to carry or store large quantities of ammunition while maximising available space.

Manufactured in the USA from virtually indestructible polypropylene, the RS-100-24 is built to withstand years of use without cracking, warping, chipping, peeling or expanding. The compact footprint makes it an excellent choice for range bags, shooting boxes and reloading benches where space is at a premium.

A textured exterior provides a secure grip while helping resist scratches, and the dependable Snap-Lock latch keeps the contents securely closed during transport. MTM's full-length mechanical hinge offers superior durability compared to traditional two-piece hinge designs and is backed by a 25-year manufacturer's guarantee. Each case also includes pressure-sensitive load labels for recording your ammunition data and features a stackable design for efficient storage.

Designed for cartridges with a maximum overall length of 2.65" (67.3 mm), the RS-100-24 securely stores up to 100 rounds of ammunition in a compact and organised format.

All deliveries include tracking and require a signature on arrival to help ensure parcels are received safely.

We offer Standard delivery (2–8 business days) and Express delivery (1–3 business days, where available), noting that remote or regional areas may take longer depending on carrier performance. Shipping costs are calculated at checkout based on location and method, with no added margin. We also offer in-store pickup from our Store and certain restricted items—such as powders, primers, and ammunition—are pickup-only due to transport restrictions. If an order is delayed, damaged, or incorrect, we ask customers to email sales@hamiltonsarmoury.com.au with their order number and issue details so we can resolve it promptly.

At Hamilton’s Armoury, we stand behind our products and aim to ensure every customer is satisfied. We accept returns on most new, unused items within 14 days of delivery, provided the item is in its original condition with all packaging, tags, components included and proof of purchase is supplied. We cannot accept returns for used or damaged items, special order or clearance items, gift cards, perishable goods, or customised/personalised products.

We offer exchanges for size, colour, or model where stock is available; if not, we can provide a store credit or refund. Once a return is received and inspected, we confirm approval and issue refunds to the original payment method within 5–10 business days, with shipping costs only refundable if the return is due to our error (such as an incorrect or defective item). Customers cover return shipping unless the item arrived incorrect, damaged, or faulty and we recommend using a trackable, insured service. Returns are sent to our Goornong, VIC address and to begin a return we ask customers to email sales@hamiltonsarmoury.com.au with their order number, reason, and photos where relevant; we respond within 1–2 business days, while noting we may refuse returns that don’t meet conditions and that this policy does not affect rights under Australian Consumer Law.
