Weatherby BRASS240 Unprimed Cases240 Wthby Mag Rifle Brass 20 Per Box

Building match-grade ammunition starts with quality brass, and Weatherby's .240 Weatherby Magnum unprimed cases give handloaders the foundation they need for consistent, reliable loads. Whether you're assembling hunting rounds for a magnum rifle or developing precision loads at the range, these cases are manufactured to the demanding standards Weatherby shooters expect. Each box contains 20 cases ready for sizing, prepping, and loading.

These unprimed rifle brass cases feature CNC-machined primer pockets and are held to strict manufacturing specifications. New brass typically arrives with some variation in finish—minor discoloration near the neck is normal and results from the annealing process, which heats and cools the brass to ensure it expands and contracts properly during firing and reloading. Before you load, plan on running these cases through your standard prep sequence: sizing, deburring, and chamfering to achieve the consistency your loads demand.

Weatherby brass is a trusted choice among hunters and precision shooters who understand that ammunition quality begins with the case. The .240 Weatherby Magnum is a specialized cartridge, and sourcing purpose-built brass rather than improvising from other magnum cases ensures your loads will perform as designed. This is the brass you reach for when precision and reliability matter.

Specifications

Frequently Asked Questions

Do I need to prep these cases before loading?

Yes. New brass should be sized, deburred, and chamfered before reloading. While these cases arrive clean and to spec, running them through your standard prep sequence ensures they're ready for consistent, safe loads.

Why does my new .240 Weatherby brass have discoloration near the neck?

That's a normal result of the annealing process—controlled heating and rapid cooling that gives the brass the flexibility it needs to expand and contract safely during firing and reloading. It's not a defect.

Is this brass suitable for hunting and range use?

Yes. These Weatherby cases are built to the standards hunters and precision shooters rely on for both hunting loads and target practice.

What does unprimed mean?

Unprimed means the cases arrive without primers installed. You'll seat primers yourself as part of your reloading process, allowing you to choose the primers that best suit your load specifications.
