These two cartridges offer impressive ballistics and are popular choices for extreme long-range shooting, hunting, and competitive shooting. This comprehensive guide will delve deep into the 338 Lapua vs 338 Edge debate, providing you with the information you need to make an informed decision. We’ll explore their ballistics, performance, reloading considerations, and overall suitability for various applications. Our aim is to provide an authoritative and trustworthy comparison, drawing upon expert knowledge and practical considerations to help you choose the right cartridge for your needs.

Understanding the 338 Lapua Magnum

The 338 Lapua Magnum (8.6x70mm) is a rimless, bottlenecked, centerfire cartridge developed in the 1980s as a joint venture between Lapua and the Finnish Defence Forces. Its primary purpose was to provide a long-range anti-personnel and anti-materiel capability for military snipers. The 338 Lapua quickly gained popularity among civilian shooters for its exceptional accuracy, flat trajectory, and impressive energy retention at extended ranges. It’s considered a magnum cartridge, designed for large game hunting and extreme long-range target shooting. The 338 Lapua is a standardized cartridge, meaning ammunition and reloading components are widely available.

Key Characteristics of the 338 Lapua Magnum

* **High Ballistic Coefficient Bullets:** Designed to use heavy, high-BC bullets for minimal drag.
* **Magnum Performance:** Delivers significant energy at long ranges.
* **Widely Available:** Ammunition and components are readily accessible.
* **Standardized Cartridge:** SAAMI-standardized dimensions ensure consistent performance.

Exploring the 338 Edge

The 338 Edge is a wildcat cartridge based on the 300 Remington Ultra Magnum (RUM) case necked up to accept .338 caliber bullets. It was developed by Shawn Carlock of Defensive Edge as a more affordable and readily available alternative to the 338 Lapua Magnum. The 338 Edge offers similar performance to the 338 Lapua but utilizes a larger case capacity, allowing for slightly higher velocities with certain bullet weights. However, because it’s a wildcat cartridge, it requires custom reamers and dies, and ammunition isn’t commercially available.

Key Characteristics of the 338 Edge

* **Wildcat Cartridge:** Requires custom reloading components and expertise.
* **High Velocity Potential:** Large case capacity allows for high velocities.
* **Based on 300 RUM:** Uses readily available 300 RUM brass as a starting point.
* **Requires Custom Chambering:** Rifles must be chambered specifically for the 338 Edge.

Ballistic Performance: 338 Lapua vs 338 Edge

When comparing the 338 Lapua vs 338 Edge, ballistic performance is a critical factor. Both cartridges are capable of delivering exceptional accuracy and range, but there are some key differences. The 338 Lapua typically pushes a 300-grain bullet at around 2750-2800 fps, while the 338 Edge can achieve slightly higher velocities, often exceeding 2900 fps with the same bullet weight. This translates to a flatter trajectory and slightly less wind drift at extreme ranges.

However, the difference in velocity isn’t always significant and can depend on various factors, including barrel length, powder type, and bullet selection. In practical terms, both cartridges are capable of reaching out to 1000 yards and beyond with ease. The shooter’s skill and the quality of the rifle and optics are often more important than the slight ballistic advantage of one cartridge over the other.

Ballistic Comparison Table (Example)

| Cartridge | Bullet Weight (grains) | Velocity (fps) | Energy (ft-lbs) | 1000 Yard Drop (inches) | 10 mph Wind Drift (inches) |
| :————– | :——————— | :————- | :————– | :————————– | :————————— |
| 338 Lapua Magnum | 300 | 2750 | 5030 | 300 | 75 |
| 338 Edge | 300 | 2900 | 5605 | 280 | 70 |

*Note: These are approximate values and may vary depending on specific load data and rifle configurations.*

Reloading Considerations: A Crucial Factor

Reloading is a common practice among shooters who use the 338 Lapua and 338 Edge, as it allows for fine-tuning the ammunition to achieve optimal accuracy and performance. However, there are significant differences in the reloading process for these two cartridges.

The 338 Lapua benefits from readily available brass, bullets, and reloading dies. Load data is also widely published, making it easier to develop accurate and consistent loads. On the other hand, the 338 Edge requires more specialized reloading knowledge and equipment. Since it’s a wildcat cartridge, you’ll need to form cases from 300 RUM brass, which can be a time-consuming process. You’ll also need custom reloading dies and carefully research load data to ensure safe and reliable performance.

Reloading Pros and Cons

**338 Lapua Magnum:**

* **Pros:** Readily available components, extensive load data, easier to reload.
* **Cons:** Brass can be more expensive than 300 RUM brass.

**338 Edge:**

* **Pros:** Potentially higher velocities, can be more cost-effective (depending on brass sourcing).
* **Cons:** Requires case forming, custom dies, more complex reloading process.

Rifle Availability and Cost

The availability and cost of rifles chambered in 338 Lapua and 338 Edge are also important considerations. 338 Lapua rifles are widely available from various manufacturers, including Accuracy International, Sako, Barrett, and Remington. These rifles range in price from a few thousand dollars to well over ten thousand, depending on the features and quality.

Rifles chambered in 338 Edge are less common and typically require a custom build. This means you’ll need to purchase a rifle action, barrel, and stock separately and have a gunsmith assemble them. While this can be more expensive than buying a factory 338 Lapua rifle, it allows you to customize the rifle to your exact specifications. Many shooters feel the custom build provides superior accuracy and performance.

Cost Comparison (Approximate)

* **Factory 338 Lapua Rifle:** $4,000 – $15,000+
* **Custom 338 Edge Rifle:** $3,500 – $12,000+ (depending on components)

Applications: Where Each Cartridge Excels

Both the 338 Lapua and 338 Edge are versatile cartridges that can be used for a variety of applications. However, there are certain areas where each cartridge excels.

The 338 Lapua is a popular choice for military and law enforcement snipers, as well as long-range target shooters and hunters. Its standardized dimensions and readily available ammunition make it a reliable and convenient option for these applications. The 338 Edge, on the other hand, is often favored by competitive shooters and long-range enthusiasts who are willing to invest the time and effort required to reload their own ammunition. Its potential for slightly higher velocities can provide a competitive edge in certain situations.

Ideal Applications

4. **High-End Trigger (e.g., TriggerTech):** Provides a crisp and consistent trigger pull.
* *Explanation:* A high-end trigger is essential for accurate shooting. Triggers like TriggerTech offer a crisp and consistent trigger pull, improving accuracy and consistency. This is a key element in achieving precision.
5. **Muzzle Brake:** Reduces recoil and muzzle rise.
* *Explanation:* A muzzle brake redirects propellant gases to reduce recoil and muzzle rise, making the rifle more comfortable to shoot and improving accuracy. This is especially important for magnum calibers like the .338 Edge.
6. **Bedding:** Ensures a solid and consistent connection between the action and the stock.
* *Explanation:* Bedding the action to the stock ensures a solid and consistent connection, improving accuracy by eliminating movement and vibration. This is a common practice in custom rifle building.
7. **Longer Barrel Length:** Maximizes velocity and ballistic performance.
* *Explanation:* .338 Edge rifles often utilize longer barrels (e.g., 30-32 inches) to maximize the cartridge’s velocity potential. This results in a flatter trajectory and improved long-range performance.
