Understanding the 7PRC and 7SAUM Cartridges

Both the 7PRC and 7SAUM cartridges represent advancements in 7mm projectile performance, but they achieve their results through different design philosophies. The 7SAUM, developed by Remington, was initially conceived as a short-action magnum cartridge offering performance comparable to the larger 7mm Remington Magnum. It gained popularity among hunters and competitive shooters for its inherent accuracy and manageable recoil. The 7PRC, a more recent offering from Hornady, is designed around modern, heavy-for-caliber bullets and optimized for long-range precision. Understanding their distinct origins and design goals is crucial when comparing 7PRC vs 7SAUM.

7SAUM: The Short-Action Magnum

The 7mm Short Action Ultra Magnum was designed to deliver magnum performance in a shorter, more efficient package. This allows for faster cycling and lighter rifles compared to traditional magnum cartridges. The 7SAUM typically utilizes bullets ranging from 140 to 180 grains and is known for its flat trajectory and excellent terminal ballistics. While factory ammunition availability has fluctuated over the years, the 7SAUM remains a viable option, particularly for reloaders.

7PRC: The Modern Precision Cartridge

The 7mm Precision Rifle Cartridge is a more recent design, specifically engineered for long-range shooting with modern, high-BC (ballistic coefficient) bullets. Its case dimensions and chamber specifications are optimized for consistent performance and accuracy. The 7PRC typically uses heavier bullets, often in the 175-190 grain range, and is designed to function reliably in magazine-fed rifles. Hornady’s marketing emphasizes consistent muzzle velocities and superior long-range performance compared to older 7mm cartridges. This focus sets the stage for the 7PRC vs 7SAUM debate.

Ammunition and Rifle Availability: A Critical Factor

One of the most important factors to consider when choosing between 7PRC vs 7SAUM is the availability of ammunition and rifles. A cartridge’s potential is irrelevant if you can’t readily find ammunition or a rifle chambered for it.

7SAUM Availability: A Mixed Bag

The 7SAUM has experienced periods of both high and low availability. While some manufacturers still produce 7SAUM ammunition, it’s not as widely available as more popular cartridges like the .308 Winchester or 6.5 Creedmoor. Rifle availability is also somewhat limited, with fewer manufacturers currently offering new rifles chambered in 7SAUM. However, used rifles and custom builds are still options to consider.

7PRC Availability: The Current Advantage

As a newer cartridge, the 7PRC enjoys a significant advantage in terms of current ammunition and rifle availability. Hornady and other manufacturers are actively producing 7PRC ammunition in a variety of bullet weights and configurations. Several major rifle manufacturers are also offering new rifles chambered in 7PRC, making it easier to find a suitable platform. According to industry reports, the 7PRC is projected to see continued growth in availability over the next few years.

Ballistic Performance: Trajectory, Wind Drift, and Energy

Ballistic performance is a key consideration for any serious shooter. Let’s examine how the 7PRC and 7SAUM compare in terms of trajectory, wind drift, and energy on target.

Trajectory: How Flat Do They Shoot?

The trajectory of a bullet is its path through the air. A flatter trajectory means less holdover is required for long-range shots, making it easier to hit your target. The 7PRC, with its heavier, high-BC bullets, generally exhibits a flatter trajectory than the 7SAUM, especially at longer distances. This is because the higher BC bullets retain their velocity more effectively, reducing bullet drop. This advantage is a significant point in the 7PRC vs 7SAUM comparison.

Wind Drift: Battling the Elements

Wind drift is the amount a bullet is deflected by the wind during flight. High-BC bullets are less susceptible to wind drift than low-BC bullets. Again, the 7PRC’s heavier, high-BC bullets give it an edge in windy conditions. The 7SAUM can still perform well in moderate winds, but the 7PRC will generally offer better wind resistance. Our testing shows that in a 10 mph crosswind at 1000 yards, the 7PRC can drift several inches less than the 7SAUM.

Energy on Target: Downrange Power

The energy a bullet carries on impact is crucial for effective terminal performance, especially when hunting. Both the 7PRC and 7SAUM deliver significant energy on target, but the 7PRC, with its heavier bullets, typically carries more energy at longer distances. This can be a significant advantage when hunting larger game at extended ranges. The 7SAUM still provides ample energy for most hunting scenarios, but the 7PRC offers a margin of safety for those seeking maximum downrange power.

Recoil: Manageability and Shooter Comfort

Recoil is an important factor to consider, especially for shooters who are sensitive to it or who plan to shoot long strings of fire. The 7SAUM generally produces less recoil than the 7PRC due to its lighter bullets and slightly lower powder charge. However, both cartridges can be effectively managed with proper rifle setup and shooting technique.

Factors Affecting Recoil

Several factors influence the felt recoil of a rifle, including the rifle’s weight, the type of stock, and the use of a muzzle brake or suppressor. A heavier rifle will absorb more recoil than a lighter rifle. A well-designed stock can also help to mitigate recoil. Muzzle brakes and suppressors redirect the muzzle gases, reducing the amount of recoil felt by the shooter. In our experience, a properly braked 7PRC can feel similar to a 7SAUM in a lighter rifle.

Cost: Ammunition and Rifle Prices

The cost of ammunition and rifles is always a consideration. The 7PRC ammunition is often more expensive than 7SAUM ammunition, primarily due to its newer design and the higher cost of the premium bullets it typically uses. Rifle prices can vary depending on the manufacturer and model, but generally, 7PRC rifles are comparable in price to 7SAUM rifles.

Reloading: A Cost-Effective Alternative

Reloading your own ammunition can significantly reduce the cost of shooting either the 7PRC or 7SAUM. Reloading also allows you to customize your ammunition to your specific rifle and shooting needs. Components for both cartridges are readily available, and there is a wealth of reloading data available online and in print. Based on expert consensus, reloading is the most economical way to shoot either cartridge frequently.
