Starline Brass .357 Magnum unprimed cases give reloaders a reliable, affordable foundation for building custom ammunition. Whether you're handloading for target practice, competition, or hunting, these 100-pack cases let you control every variable in your round—powder charge, bullet weight, and primer selection—to dial in performance exactly how you want it. Starline brass has built a reputation for consistent quality and competitive pricing in the reloading community, making it a smart choice when you need volume without breaking the bank.
Unprimed cases mean you start with a blank slate. You'll add your own primer, powder, and bullet in the sequence that suits your workflow and equipment. This gives handloaders maximum flexibility—especially useful if you're experimenting with different primer types or load recipes, or if you already have priming equipment dialed in to your preferred method.
A 100-case pack is a practical size for serious reloaders: enough to get a solid session in without overcommitting to one brass lot, and a good way to test Starline's consistency before you buy in larger volume. .357 Magnum brass is a workhorse for both wheelguns and lever actions, so you'll find plenty of load data and component availability to support your reloading bench.

No, these are unprimed cases. You will need to add primers yourself as part of your reloading process.
To complete a round, you'll need primers, powder, bullets, and standard reloading equipment (press, dies, scale, and calipers). The specific powder and bullet weights depend on your load recipe and intended use.
Starline is known in the reloading community for consistent case dimensions and durability. The 100-pack is a good way to test the quality before committing to larger quantities.
