Product Information

The R-100 provides excellent protection for reloads and when the rounds are in the down position, they are protected by four special fingers which keep your bullets from hitting the bottom of the box and causing tip damage (which can change flight characteristics). It comes with adjustable inner trays which offer two height positions for different cartridge lengths. Ammo in picture is not included.

  • Polypropylene construction with a scuff resistant, textured finished that will not crack, ship, contract, expand or warp
  • An integral "living hinge" with a 10-year guarantee
  • Snap-Lok latch to prevent spilling
  • Folding handle for easy storing and stacking
  • Pressure sensitive load label provided for recording load and sight data

Handles the 300 Win Mag

By Steve P. on Aug 30, 2020
I have used these since MTM starting making them. This particular size is perfect for the 300 Win Mag and we shoot large volumes of precision ammo at our range and the 100 pack boxes are perfect. I bought red and green this time and they sent me two reviews, but we just use different colors for different guns. Great workmanship and I'm using boxes at least 35 years old, maybe older and have no problems.

Perfect for 338 Lapua

MTM Quality

By David E. on Nov 27, 2018
MTM is the only ammo box/holder I will use, I have 2 that are over 20 years old and still look and function as new!
