Lapua 7.62×39 Brass Cases

The 7.62×39 is best known as the cartridge used in the AK-47 and other military-style rifles. However, the cartridge also has applications in competition, target shooting and hunting. Lapua 7.62×39 Brass gives reloaders a premium case designed for consistent handloads, rather than the military or surplus brass often associated with this cartridge.

What Makes Lapua 7.62×39 Brass Different?

Lapua describes its 7.62×39 case as match-quality brass. The company also states that it offers a significant advantage over military-quality cases for competition use. That distinction is important because military and surplus 7.62×39 brass can vary more from case to case.

Lapua controls the brass, forming and drawing processes during manufacture. As a result, the cases provide a more consistent starting point for precision handloading. The company also controls the primer pockets and flash holes to tight tolerances across its brass range.

The case itself forms part of every handload. Therefore, differences between cases can add another variable during load development. Starting with more uniform brass reduces the need to sort and correct cases before testing a load.

In practice, that gives the reloader more control over the ammunition. Powder charge, primer, bullet and seating depth still need careful control. However, reducing variation in the brass removes one more variable from the process.

Lapua 7.62×39 Brass and Case Preparation

Every cartridge case changes during firing and resizing. The case expands to fit the chamber when fired. Afterward, sizing returns it to dimensions suitable for another loading cycle.

Lapua controls the heat treatment of its brass during manufacture. The company anneals the neck and shoulder to manage the effects of forming and working the material. This helps the brass maintain the properties needed for repeated firing and resizing.

The visible colour around the neck and shoulder of new Lapua cases comes from this factory annealing process. Importantly, Lapua leaves the colour in place rather than polishing it away. The mark is therefore a normal feature of the case, not a sign of a problem.

Primer pockets and flash holes also matter to precision reloaders. For example, consistent primer-pocket dimensions help maintain a uniform primer fit. Likewise, consistent flash-hole dimensions help reduce another possible source of variation during ignition.

7.62×39 Competition and Hunting Applications

The 7.62×39 has a long military history, but its use extends beyond military rifles. Lapua identifies the cartridge for competitive shooting and hunting, and specifically positions its brass as a match-quality component. This makes Lapua brass particularly interesting for shooters who want to improve the consistency of their 7.62×39 ammunition.

For competition and target shooting, consistent cases can make load development easier. Instead of starting with mixed military or surplus brass, the reloader can work from a more uniform batch.

The cartridge also has suitable hunting applications where local regulations and rifle suitability allow its use. At the same time, its compact size makes it practical in a range of compatible rifles.

Lapua also produces components for the cartridge, including a 123 grain FMJ bullet. This gives reloaders another option when developing a complete component combination around the 7.62×39. (Lapua)
