The MTM Case-Gard SB-200 multi-caliber rimfire rifle ammo box is built for shooters who need organized, reliable storage that handles everything from .22 LR to .17 HMR. Whether you're a competition small-bore shooter, a varmint hunter, or someone who just likes to plink, this polypropylene case keeps your rounds safe and sorted. The rust-resistant design means it'll hold up to field use and range days without breaking down—no cheap plastic that cracks in the truck bed.

The SB-200 stores 100 rounds in the down position, making it easy to grab ammo quickly during a match or hunting session. The design also accommodates two full 50-round boxes in the center section, so you can organize by load, velocity, or bullet weight without having to dump everything loose into the main cavity. That flexibility matters when you're testing loads or trying different ammunition for accuracy work.

Built tough enough for serious shooters but simple enough for casual range trips, the SB-200 is a no-frills ammunition storage solution that does the job well. The rust polypropylene holds up to occasional moisture and won't degrade your ammo.
