A collection of .300 BLACKOUT ammunition and fired casings housed in two MTM plastic storage boxes. The lot comprises 100 Rounds .300 BLACKOUT. The green MTM box contains approximately fifty loaded rifle cartridges, each with a brass casing and a copper-jacketed, pointed projectile featuring a distinct orange-red tip. Visible headstamps on these rounds include ‘LC 09’ and ‘LC 10’. The red MTM box contains approximately fifty brass rifle casings, which appear to be fired due to the absence of projectiles and visible primer strikes. Headstamps on these casings include ‘WCC 09’ and ‘WCC 07’. In both the green and red boxes, a single, complete brass-cased, standard copper-jacketed rifle cartridge (lacking a red tip) is laid horizontally across the bulk contents. The plastic boxes are modern and feature flip-top lids, consistent with MTM Case-Gard designs.
