If you're feeding a .340 Weatherby Magnum, you already know the value of starting with good brass, and this is about as good as it gets for the caliber. These unprimed cases are produced for Weatherby by Norma Precision, a name that carries real weight in the reloading world for dimensional consistency and clean annealing. Each case comes with a CNC-machined primer pocket held to match-grade specs, so you get uniform primer seating and a solid foundation for working up loads that shoot the same every trip to the range.
The .340 Weatherby Magnum is a serious big game cartridge. Roy Weatherby introduced it in 1962 to fill the gap between his .300 and .378, and it pushes a 250 grain .338 bullet right around 2,950 fps. That kind of velocity means real pressure and real recoil, so the brass under your load needs to be up to the task. Starting with quality Norma stock gives you cases that hold their shape through repeated firings and resizing, which is exactly what you want when you're loading for elk, moose, big bears, or long reaching plains game.
These are unprimed, so you've got full control over your primer and powder combination. As with most quality rifle brass, give the cases a check before loading. A quick pass to size, deburr, and chamfer the mouths gets everything uniform and ready. You may also notice a slight discoloration near the neck from the annealing process, which is completely normal and a sign the brass was properly heat treated during manufacturing.
For anyone running a Mark V or any other rifle chambered in .340 Weatherby, having a stash of reliable, reloadable brass on hand is the difference between shooting when you want and waiting on hard to find factory ammo. This is the brass to build your handloads around.
These cases are produced for Weatherby by Norma Precision, one of the most respected names in the reloading industry. Norma brass is known for tight dimensional tolerances and consistent annealing, which is why Weatherby sources from them. You're getting premium brass under the Weatherby label.
These are unprimed cases, so you'll add your own primer, powder, and bullet. The .340 Weatherby Magnum uses a large rifle magnum primer. Before loading, it's good practice to size, deburr, and chamfer the case mouths to get everything uniform.
That stain comes from the annealing step during manufacturing, which is a normal part of how quality brass is made. Annealing relieves stress in the neck and shoulder so the brass lasts longer through repeated firings. It's a sign the cases were properly heat treated, not a defect.
It's a hard-hitting big game cartridge that drives a 250 grain .338 bullet around 2,950 fps. That makes it a strong choice for elk, moose, large bears, and heavier plains game at longer ranges. Handloading your own brass lets you tune a load that squeezes the most out of the caliber.
