Description
Starline has built its reputation one case at a time, and this .38 Super +P brass is a good example of why handloaders keep coming back. These are brand new, unprimed cases with the standard semi-rimmed head design and internal dimensions that match the .38 Super family, so they drop right into your existing dies and load data. The brass runs roughly 0.893 to 0.898 inches in case length and uses a small pistol primer.
What Makes Starline 38 Super +P Brass Worth Loading
Starline runs their own facility in Sedalia, Missouri, and the attention shows. The brass is vertically drawn during manufacturing, which gives you more uniform wall thickness, and the cases are annealed between draws for consistent metallurgy across every lot. Each case is inspected before it ever hits the bag. Reloaders who run these describe them as clean, polished, and dead-on when it comes to sizing, with cases that hold up well through repeated loading cycles.
Loading the 38 Super +P for the Range or the Match
The .38 Super has long been a darling of the competition crowd, especially in 1911 and 2011 platforms where it makes major power factor without beating up the shooter. The heavy-duty +P brass is built to handle the higher pressures that come with those hotter loads, giving you a durable foundation for match ammo. It is equally at home in lighter plinking loads if you just want to feed a range gun affordably.
A Few Things to Know Before You Start
These are component cases only, not loaded ammunition, so you will need primers, powder, and bullets to turn them into working rounds. As with any new bulk brass, it is smart to full-length size, trim to length, and chamfer the case mouths before your first loading. Do that bit of prep and you have got a batch of brass that will reward you with a long, reliable service life.
