Weatherby Unprimed Cases 257 Wthby Mag Rifle Brass$120.90
Availability: In Stock
If you're handloading ammunition for a .257 Weatherby Magnum rifle, the foundation of every accurate round starts with consistent, quality brass. Hornady 8631 unprimed cases for the .257 Weatherby Mag give you 50 cases per box—the brass component you need to build cartridges with repeatable pressures and velocities. These unprimed rifle cases are manufactured to tight tolerances, meaning the case walls are as uniform as possible from round to round, a detail that benchrest and long-range shooters have always understood matters.
Consistency is what separates decent reloads from great ones. When Hornady brass arrives at your bench, every case in the lot is virtually identical to the next. That uniformity translates into predictable chamber fit, uniform bullet seating, and better concentricity—the concentricity that helps ensure your bullet releases evenly when fired, supporting both velocity consistency and accuracy downrange. Because Hornady invests in the quality of their brass production, you'll also get more useful reloads from each case before it's time to retire it.
The .257 Weatherby Mag is a potent magnum cartridge, and it demands brass that won't let you down. Whether you're developing a new load for long-range hunting or fine-tuning a precision rifle load, starting with Hornady's tightly-controlled unprimed cases keeps variables where they belong—in your powders, primers, and bullets, not in the brass itself.

Unprimed means these cases come without primers installed. You'll need to seat primers yourself as part of the reloading process. This gives you flexibility to choose primers that match your load specifications.
Yes, these cases are designed for the .257 Weatherby Magnum chambering. Confirm that your rifle is chambered in .257 Weatherby Mag (not a different .257 cartridge) before purchasing.
Hornady brass is designed for longevity due to consistent wall thickness and tight manufacturing tolerances. The exact number of reloads depends on your load data, pressure levels, and inspection practices. Inspect cases regularly for signs of wear, cracking, or excessive primer pocket expansion.
One box contains 50 cases. For initial load development and testing, this may be sufficient; for extensive testing across multiple charge weights or primers, you may want additional boxes to maintain consistency across test groups.
