Lapua 300 WSM Brass Cases (100)

Description

The 300 WSM case

Over the last 20 years the firearms industry has seen a rise in the popularity of rifle cartridges designed to equal or exceed the performance of the traditional belted magnums but without some of the limitations of cartridge overall length. Among the multitude of new cartridges, one of the most successful of these has been the 300 Winchester Short Magnum (WSM).

The 300 WSM provides many competitive features and advantages over legacy belted magnum cartridges, delivering energy equal to the 300 Win Mag and conveniently integrated into a short action rifle design. These features include enhanced rigidity, a shorter bolt throw, a compact powder column, and reduction in weight – all attributes which enhance performance during the hunt or on the firing line.

Available in 2024, Lapua introduces 300 WSM cartridge cases, finally providing a superior quality case component for its loyal followers. Lapua cartridge cases are known to exceed the quality and longevity of all others offered on the market. Lapua uses only the highest quality materials and manufacturing processes to satisfy the demands of long-range shooters who seek the highest levels of precision from their 300 WSM firearm platforms.

The base of the case.

The Lapua case heads are drawn exceptionally hard for unmatched reloadability and for an exceptionally long-life cycle to serve top shooters time and time again. The brass dimensions remain constant and will hold primers tight in their pockets even after many reloadings.

The brass body.

The brass body section of Lapua cases is hard and resilient for unmatched durability. It is easy to extract after firing, whether the reloader opts for full sizing or neck sizing only.

The case neck.

Strict tolerances in concentricity and wall thickness are used in manufacturing of the case neck. The neck and shoulder of Lapua cases are annealed to withstand repeated reloading.
