The Hornady .38 Super Comp Unprimed Handgun Cartridge Cases provide a premium, elite-tier structural foundation custom-engineered for competitive shooters and high-volume handloaders running modern semi-automatic pistols. Unlike traditional semi-rimmed ammunition in this class, the specialized .38 Super Comp configuration utilizes a true modified rimless design that drastically minimizes the physical rim width to guarantee ultra-smooth feeding from both single- and double-stack magazines. Built to withstand intense high-pressure thresholds across demanding USPSA and IPSC competitive matches, each component case features exceptionally tight wall concentricity and optimized hardness to prevent feed binding or premature rim shearing. Hornady treats these small-lot production cases to rigid pressure calibration testing to deliver perfectly uniform case expansion and precise bullet seating, maximizing downrange velocity uniformity. Packaged as a bulk box of 200 unprimed component cases, this reload-friendly brass delivers identical lot-to-lot consistency to save meticulous marksmen from extensive time sorting or trimming at the bench.
