What This Norma Weatherby Mag Brass Is and Who It Is For
The 340 Weatherby Magnum is a hard hitting .338 caliber belted magnum built to reach out and drop large game with heavy bullets at high velocity. It is a serious elk, moose, and big bear cartridge with plenty of long range authority. This brass is for the big game handloader who wants consistent, durable cases behind heavy .338 bullets and stout charges.
Factory 340 Weatherby ammunition is costly and hard to find, so reloading with this Norma Weatherby Mag Brass is the practical way to keep the rifle fed and tune loads precisely.

Specifications Worth Knowing
Each box holds 50 rounds of new 340 Weatherby Magnum brass. Norma builds these cases with in house tooling held to tolerances of only a few thousandths of a millimeter, which keeps capacity and headspace uniform, and that consistency matters when you drive heavy bullets at magnum velocity. Uniform brass helps control both pressure and velocity spread. This is component brass and not loaded ammunition, so you supply the primers, powder, and .338 bullets to build your load.
Practical Use, Care, and Compatibility
Full length size to fit your chamber, trim to a uniform length, and inspect the belt and case head after each firing given the pressures involved. With disciplined prep this Norma Weatherby Mag Brass will serve through multiple reloads within published limits. It fits any rifle correctly chambered for the 340 Weatherby Magnum. Match it with .338 bullets and gear from our Apparel and Gear collection.
Heavy Bullet Reach for Big Game
The 340 Weatherby earns its keep where large game meets long range. It drives heavy .338 bullets with the velocity to shoot flat and the energy to anchor elk, moose, and big bear well past where lesser cartridges run out of steam. That performance rests on brass that can take a stout charge and stay consistent.
Handloading lets you match a tough, heavy bullet to your rifle and build a load that prints exactly where you aim.
Load Development and Long Term Value
Given the recoil and pressure of a magnum this size, develop your load in careful steps and inspect the belt and case head after every firing. Full length sizing keeps a hunting rifle feeding smoothly under stress.
Because factory ammunition for this cartridge is both pricey and scarce, buying fifty matched cases up front secures an affordable, consistent supply for years of practice and hunting.
Ordering, Care, and Value
Inspect your box of fifty on arrival and store the cases in a dry, labeled container so a matched big game lot stays together. Unprimed brass keeps for years when clean and dry, so you can load in batches as the season approaches. Because factory ammunition for this cartridge is both costly and scarce, quality component brass pays for itself across repeated firings, and it lets you build the exact heavy bullet load your rifle prints tightest. For serious big game work, that control is worth every bit of the effort.
For the 340 Weatherby big game hunter, this Norma Weatherby Mag Brass is a dependable choice. Ships direct to your door, no FFL required.
