Specifications and details

This listing covers a 50 count quantity of new 300 H&H Magnum brass. The belt at the case head provides positive headspace, while the long sloping shoulder feeds smoothly through bolt action magazines. That combination is part of why the cartridge remains a respected choice for large game around the world.

Norma cases are known for their clean finish and dimensional consistency, which helps deliver even neck tension and predictable pressures during load development. Starting with brass this uniform means fewer variables when you chase accuracy at long range.

Reloading, care, and compatibility

Confirm case length before your first loading and trim as needed, then use published 300 H&H Magnum data with a large rifle magnum primer. Start below maximum and work up while watching for pressure signs, and store your brass dry and clean between sessions. Because this is a belted case, pay attention to shoulder setback and consider partial resizing to extend case life.

This brass runs with standard 300 H&H Magnum dies and chambers in any rifle cut for the cartridge. Learn more about the maker at Norma, then browse our apparel and gear collection for bullets, primers, and more.

The 300 H&H heritage

The 300 Holland and Holland Magnum is a genuine classic, a belted cartridge that helped define the modern magnum era and earned its stripes on hunts around the world. Its long, gently sloping shoulder feeds like butter through a bolt action, and its ballistics have kept it relevant long after flashier cartridges came and went. For the handloader, it rewards attention with excellent accuracy and reach.

Because this is a limited arrival, availability is the real story here. Brass for older magnums can vanish from shelves for long stretches, so a chance to buy fresh, premium cases in quantity is worth acting on. A 50 count lot gives you enough to develop a load and still have cases in reserve.

Store your brass in a cool, dry place and it will wait for years without any loss of quality. When you are ready, this is the foundation for the kind of confident, hard hitting hunting load the 300 H&H was born to deliver in the field.
