This 200-count pack of Hornady unprimed brass is built for the .38 Super Comp cartridge, the rimless variant that feeds and headspaces cleaner in high-capacity race guns and competition 1911 platforms. Worth knowing before you load: Hornady carries this under part number 8734 as .38 Super Comp, which differs slightly from traditional semi-rimmed .38 Super Auto. If you shoot an Open gun, double-stack 2011, or any pistol chambered specifically for Super Comp, this is the brass you want on the bench.
Hornady builds these cases to tight tolerances so you get consistent charges and pressures round after round. The company measures for wall concentricity and runs cases through a pressure calibration test to confirm uniform expansion when fired. That attention to uniform wall thickness, case weight, and internal capacity is what keeps velocity spreads down and makes your load data behave the way it should from one batch to the next.
Concentric case walls matter more than most folks give them credit for. They let the bullet seat straight in the case and chamber properly, then release cleanly on firing. For the Super Comp crowd chasing a major power factor with a flat-shooting, soft-recoiling load, that consistency translates directly into tighter groups and more predictable chrono numbers.
Hornady treats brass as the backbone of an accurate cartridge rather than a throwaway component, and the payoff is more reloads per case before the brass is done. Starting with new, unprimed cases also means you know exactly what you've got: no mixed headstamps, no mystery range pickups, and a uniform lot to work your load development around. Prime, charge, seat, and crimp to your recipe and you're ready to run.
Not exactly. Hornady part number 8734 is .38 Super Comp, a rimless version designed to feed and headspace more reliably in high-capacity competition pistols. If your gun is chambered specifically for .38 Super Comp, this is the correct brass. Double-check your chamber before loading, since traditional .38 Super Auto is semi-rimmed and can behave differently.
It comes unprimed. You'll need to add your own primers, powder, and bullets to complete the cartridges. Starting with new, unprimed brass gives you a clean, uniform lot to build your load data around.
Hornady builds these to tight tolerances and treats brass as the foundation of an accurate cartridge rather than a commodity, so you tend to get more reloads per case than with commodity brass. Actual case life depends on your pressures, sizing practices, and how hard you push your loads. With reasonable Super Comp pressures and good reloading habits, these hold up well over multiple cycles.
The uniform wall thickness, consistent case weight, and matched internal capacity help keep velocity spreads tight, which matters when you're chasing a steady power factor. Concentric case walls also let bullets seat straight and release cleanly for better accuracy. That combination is why a lot of Open and 2011 shooters build their match ammo on Super Comp brass.
