The MTM Case-Gard R-100-MAG-10 Deluxe Rifle Ammo Box provides dedicated, heavy-duty storage for up to 100 rounds of large-diameter magnum and short-magnum rifle cartridges. Moulded from scuff-resistant, high-impact polypropylene in forest green, this case incorporates an integrated mechanical hinge, Snap-Lok latch, and a fold-flat carry handle. Inside, reversible tiered trays allow users to position cartridges in either a bullet-up or bullet-down orientation while four moulded fingers per cell suspend the case shoulder, keeping delicate projectile tips from contacting the bottom of the box during transit.

Who is the MTM Deluxe Rifle Ammo Box With Handle - 100 Round Fits WSM WSSM Ultra Magnum for?

• Handloaders and precision hunters managing large batches of magnum ammunition — requires high-capacity rifle ammunition storage boxes that protect custom-seated projectiles, utilizing internal suspension fingers to maintain ballistic tip integrity across cartridges up to 3.75 inches (95.25 mm) Max OAL bullet down.
• Long-range target competitors shooting short magnums — requires a dedicated 100-round capacity container engineered for wide-body cases like 6.5 PRC and WSM calibres, providing quick access and secure cell fitment for rounds up to 3.24 inches (82.3 mm) Max OAL in the bullet-up configuration.

Less suitable for: Extra-long magnum cartridges with an overall length exceeding 3.75 inches (such as .338 Lapua Magnum), which require specialized extra-large-calibre ammunition boxes; and standard-diameter non-magnum rifle cartridges (such as .308 Winchester or .30-06 Springfield), which fit better in standard-diameter 100-round ammo boxes to prevent excess chamber rattle.
