Nosler Unprimed Brass Rifle Cartridge Cases 50/Ct 6.55X55Mm

Nosler unprimed brass rifle cartridge cases in 6.5x55mm Swedish Mauser are purpose-built for handloaders who demand consistency and reliability in every round. This 50-count box of premium brass comes fully prepped and ready to load—Nosler has already handled the tedious case preparation so you can focus on developing and shooting accurate loads. Whether you're fine-tuning a precision rifle load or building ammunition for a classic Swedish Mauser, this brass gives you a clean starting point with minimal additional prep work.

What sets Nosler brass apart is the attention to detail baked into every case before it leaves the factory. Each piece arrives chamfered, deburred, and sized to proper length. Flash holes are deburred and checked for alignment, and every case is hand-inspected to confirm it meets Nosler's dimensional standards. The brass is also weight-sorted to within ±0.5 grains, so you're starting with cases matched for consistency—a real advantage when you're chasing tight groups or load development data. All of that prep work means less time at the bench getting cases ready and more time loading and testing.

Built for case life and reloadability, Nosler Premium Brass is made from quality materials that reward careful handloading with multiple firings. The unprimed cases carry the Nosler headstamp and come in a convenient 50-case box, enough for a full session of load development or a solid batch of finished ammunition. If you shoot a 6.5x55mm and want to cut your case prep time without compromising quality, this is a smart choice.

Frequently Asked Questions

What does "fully prepped" mean, and how much additional work do I need to do?

Nosler's fully prepped brass arrives with case mouths chamfered and deburred, flash holes cleaned and checked, and all cases full-length sized and trimmed to proper length. You can load these cases immediately without additional prep work—just inspect them visually and begin handloading.

Will these cases work in a Swedish Mauser rifle?

Yes. The 6.5x55mm (also known as 6.5x55mm Swedish Mauser) is the cartridge for classic and modern rifles chambered in that caliber. These unprimed cases are designed for that cartridge.

How many rounds is this box good for?

This box contains 50 unprimed cases. Since they're designed for multiple reloads with proper handloading technique and care, a single case can be reloaded many times over its life, making this a good starting quantity for load development or a substantial batch of finished ammunition.

Are these cases already sized, or do I need to full-length resize them before loading?

These cases come full-length sized from the factory, so they're ready to load as-is. You can begin the handloading process without additional sizing.
