Weatherby BRASS7MM Unprimed Cases7mm Wthby Mag Rifle Brass 20 Per Box
If you're loading for your Weatherby 7mm Magnum rifle, Weatherby BRASS 7mm Unprimed Cases give you a foundation built to match the precision your rifle demands. This 20-pack of unprimed brass is engineered for hunters and precision shooters who want consistency in their handloaded ammunition. Starting with quality brass means fewer variables when you're working up loads, and that matters whether you're hunting elk at distance or fine-tuning groups on the range.
These cases come CNC-machined with precise primer pockets that meet Weatherby's strict grade specifications. The manufacturing process includes annealing—a controlled heating and rapid cooling cycle—that ensures the brass has the flexibility to expand and contract properly through the firing and reloading cycle, and helps the case hold the bullet securely. You may notice a slight discoloration near the neck; that's a natural result of the annealing process and doesn't affect performance.
Before you start reloading, plan to size, deburr, and chamfer the cases. The manufacturing and shipping process means the case mouths may not be perfectly round right out of the box, so taking those prep steps will give you the consistency you're after. For hunters and handloaders who demand match-grade components, Weatherby brass is a proven choice.
