The MTM CASE-GARD J-20 series ammunition cases stand as a beloved choice among rifle enthusiasts globally. Crafted from virtually indestructible polypropylene, these cases offer unparalleled durability, remaining impervious to warping, cracking, chipping, peeling, expansion, or contraction. Available in five sizes, the CASE-GARD J-20s ensure all rounds are stored in a bullet-up position. Recognizing the preferences of some reloaders who prefer to avoid direct contact between the lid and their bullets, the lid dimensions are tailored accordingly. Remarkably, many reloaders have expanded the case up to half an inch without experiencing any adverse effects on accuracy, further testament to the versatility and reliability of these cases.
