Understanding the .338 Caliber Cartridge Landscape
The .338 caliber has established itself as a powerhouse in long-range shooting, offering a sweet spot between manageable recoil and devastating downrange energy. Both the .338 Lapua Magnum and the .338 Norma Magnum are designed for extreme distances, but they achieve this performance through different approaches.
A Brief History of the .338 Lapua Magnum
The .338 Lapua Magnum was developed in the 1980s as a military sniper cartridge, designed to offer superior performance over existing .30 caliber options. Its primary goal was to provide effective engagement ranges beyond 1,000 meters, with the ability to defeat body armor. Lapua, a Finnish ammunition manufacturer, spearheaded the development, resulting in a cartridge that quickly gained popularity among military and law enforcement agencies worldwide.
The Emergence of the .338 Norma Magnum
While the .338 Lapua Magnum dominated the long-range scene for years, the .338 Norma Magnum emerged as a strong contender in the late 2000s. Developed by Jimmie Sloan of Norma Precision, the .338 Norma Magnum was designed to offer comparable performance to the .338 Lapua Magnum but with improved feeding reliability in magazine-fed rifles. This was achieved by optimizing the case dimensions and shoulder angle. The .338 Norma Magnum quickly gained traction among competitive shooters due to its inherent accuracy and reliable feeding.
.338 Norma vs Lapua: A Detailed Comparison
Let’s delve into a detailed comparison of the .338 Norma vs Lapua, examining their key characteristics and performance attributes. This will provide a clear understanding of their strengths and weaknesses.
Case Dimensions and Design
* **.338 Lapua Magnum:** Features a longer case with a rebated rim, which can sometimes lead to feeding issues in certain rifles. The case capacity is slightly larger.
* **.338 Norma Magnum:** Employs a shorter, wider case with a less pronounced shoulder angle. This design promotes smoother and more reliable feeding from magazines, a significant advantage in rapid-fire scenarios.
Ballistic Performance
Both cartridges offer exceptional ballistic performance, but subtle differences exist:
* **.Muzzle Velocity:** Typically, the .338 Lapua Magnum can achieve slightly higher muzzle velocities, particularly with heavier bullets. However, the difference is often marginal.
* **.Trajectory:** Due to its higher ballistic coefficient (BC), the .338 Lapua Magnum generally exhibits a flatter trajectory at extreme ranges. However, high-BC bullets are also available for the .338 Norma Magnum, minimizing this difference.
* **.Energy:** Both cartridges deliver substantial energy downrange, capable of ethically taking large game at extended distances. The .338 Lapua Magnum might hold a slight edge in retained energy due to its higher initial velocity.
Recoil
Recoil is a significant consideration for any long-range cartridge. Both the .338 Lapua Magnum and the .338 Norma Magnum generate substantial recoil, but the perceived recoil can vary depending on the rifle, muzzle brake, and shooter’s technique.
* **.Recoil Impulse:** Due to its higher bullet weight and potentially higher velocity, the .338 Lapua Magnum generally produces a slightly higher recoil impulse.
* **.Felt Recoil:** The perceived recoil can be influenced by factors such as the rifle’s weight, stock design, and the effectiveness of the muzzle brake. With proper setup, both cartridges can be manageable, but extended shooting sessions can still be fatiguing.
Accuracy
Accuracy is paramount in long-range shooting. Both the .338 Lapua Magnum and the .338 Norma Magnum are inherently accurate cartridges, capable of producing sub-MOA (minute of angle) groups in well-built rifles with quality ammunition. According to expert consensus, the .338 Norma Magnum often exhibits slightly better accuracy potential due to its optimized case design and more consistent feeding.
Availability and Cost
* **.338 Lapua Magnum:** Ammunition and components are widely available from various manufacturers, making it easier to find suitable loads. However, the cost per round is generally higher.
* **.338 Norma Magnum:** Ammunition and components are becoming increasingly available, but the selection might be slightly more limited compared to the .338 Lapua Magnum. The cost per round is often slightly lower.
