$62.86
The Weatherby .340 Wby Mag unprimed brass offers a solid foundation for handloaders who want to develop premium ammunition for one of the industry's most capable magnum cartridges. These unprimed cases come 20 per box and are manufactured to Weatherby's exacting standards, featuring CNC-machined primer pockets that promote consistency shot to shot. If you're building .340 Weatherby Magnum loads for long-range hunting or precision shooting, starting with quality brass makes a measurable difference in accuracy and case life.
Weatherby .340 Wby Mag unprimed brass is a popular choice among serious hunters and reloaders because the base quality is already there—you're buying cases that can handle the pressures these magnum loads demand. That said, new brass does require proper prep work before you start loading. You'll want to size, deburr, and chamfer the cases as part of your preparation routine, since the manufacturing and shipping process can leave the case mouths slightly out-of-round. This is normal and expected, and a few minutes at the reloading bench will get them ready to go.
You may notice a slight discoloration near the neck on some cases—this is a byproduct of the annealing process Weatherby performs during manufacturing. That annealing step is actually a feature, not a flaw. It heats the brass to a precise temperature and then cools it rapidly, which gives the material the flexibility it needs to expand and contract reliably under the pressure of a magnum load while maintaining a secure grip on the bullet. That thermal cycling ensures your cases will perform consistently through multiple reloadings.
