Understanding the Cartridges
The 7mm PRC: A Modern Marvel
The 7mm PRC, developed by Hornady, represents a modern take on the 7mm cartridge. It quickly gained popularity due to its well-balanced performance, offering excellent ballistics without the excessive powder capacity of some of its contemporaries. It was designed from the ground up for long-range shooting and hunting, aiming to provide a flat trajectory, good wind resistance, and sufficient energy on target at extended distances. The 7mm PRC uses a non-belted case design, utilizing a shoulder angle optimized for consistent performance. This, combined with its relatively efficient powder usage, contributes to its reputation for accuracy and extended barrel life. It has rapidly become a favorite of those seeking accuracy and versatility in the field.
The 28 Nosler: Pushing the Velocity Envelope
The 28 Nosler, introduced by Nosler, is a different beast altogether. It’s built around the idea of maximizing velocity. The 28 Nosler is based on a shortened 404 Jeffery case, providing a significant powder capacity designed to drive heavier bullets at very high velocities. This cartridge’s primary goal is to achieve exceptionally flat trajectories and increased energy on target at longer ranges. Its design philosophy favors raw power and distance. This translates to impressive downrange performance, but it also means higher recoil and potentially shorter barrel life. The 28 Nosler has carved its niche as a serious long-range performer, particularly favored by those seeking to reach extreme distances.
Delving into Ballistic Performance
Bullet Selection and its Impact
Both cartridges are designed to launch heavy-for-caliber bullets. Bullet selection is crucial for maximizing their long-range performance. The 7mm PRC generally handles bullets in the 160-195 grain range. These bullets, with their high ballistic coefficients, excel in resisting wind drift and retaining velocity over long distances. The 28 Nosler, with its larger case capacity, frequently pushes bullets from 160 to 195+ grains. The availability of high BC (ballistic coefficient) bullets in both calibers allows for excellent performance at extreme ranges. The bullet selection, therefore, significantly influences the wind drift, drop and retained energy at the target.
Velocity and Trajectory: A Head-to-Head Battle
The 28 Nosler typically boasts higher muzzle velocities, especially when using the same weight bullets, due to its larger powder capacity. This translates into a flatter trajectory, meaning less bullet drop at longer distances. However, the 7mm PRC, with its more efficient design, achieves impressive velocities too. Trajectory is a critical factor in long-range shooting because it determines how much adjustment you need to make for bullet drop at various distances. The 28 Nosler, by virtue of its higher velocity, often has a slight advantage in flatter trajectories. But the 7mm PRC’s inherently better efficiency can result in less drop, depending on the loads used. The specific loads and bullet choices for each cartridge will ultimately determine which offers the flattest trajectory.
Energy at Impact: Reaching the Target with Force
Energy on target is a key consideration, especially for hunting. Both cartridges deliver significant energy at long distances. The higher velocity of the 28 Nosler gives it a slight edge in retained energy at very long ranges, especially when using heavier bullets. The 7mm PRC, however, offers more than sufficient energy for hunting most big game species at typical hunting ranges. The crucial element is ensuring sufficient energy to ensure ethical and effective hunts. The amount of energy is determined by the muzzle velocity, bullet weight, and its ballistic coefficient.
The Accuracy Equation
Factors Influencing Accuracy
Accuracy is affected by several factors, including rifle quality, ammunition quality, and the shooter’s skill. Both cartridges can achieve sub-MOA (Minute of Angle) accuracy with high-quality rifles and handloaded ammunition. The consistency of the ammunition is particularly important. Handloading allows shooters to fine-tune their loads for optimal performance. Rifles chambered for both the 7mm PRC and the 28 Nosler are available in varying qualities, impacting accuracy. The quality of the barrel, in particular, is a crucial factor for achieving consistent accuracy.
Real-World Accuracy Experiences
Shooters often report excellent accuracy with both cartridges. The 7mm PRC’s more manageable recoil can allow for faster follow-up shots, potentially increasing the hit probability. The 28 Nosler, with its higher velocity and flatter trajectory, might offer slightly better accuracy at extreme distances when combined with a shooter’s experience and well-tuned rifle. Ultimately, consistent accuracy hinges on factors outside the cartridge itself, including the rifle, ammunition, optics, and the shooter’s skills and practice.
Managing Recoil: A Balancing Act
Calculating Recoil Energy
Recoil energy is calculated based on factors like the bullet weight, powder charge, and rifle weight. The 28 Nosler, with its higher powder charge and often heavier bullets, produces significantly more recoil than the 7mm PRC. The 7mm PRC typically has more manageable recoil, making it more comfortable to shoot for extended periods.
Perceived Recoil and its Impact
Perceived recoil, or the felt recoil, depends on several factors, including the physical characteristics of the shooter, the rifle’s weight and design, and the presence of any recoil-mitigating devices. The higher recoil of the 28 Nosler can make it more challenging to maintain a stable shooting position and may require more practice to master. The more manageable recoil of the 7mm PRC allows for more comfortable shooting experiences.
Practical Considerations in the Field
Rifle Availability and Associated Costs
Both cartridges are gaining popularity, leading to increased availability of rifles. However, the 7mm PRC currently enjoys wider availability. The prices vary by manufacturer and the features of the rifle. While the differences might be marginal, it’s always a good idea to see what is on offer and compare them on the market. The decision on what the best choice for you should always take into consideration the long-term financial commitments that come with this hobby, and the availability of the rifle.
Ammunition Cost and Its Availability
Ammunition cost is another crucial factor. Both factory ammunition and reloading components are readily available for both cartridges, but prices can fluctuate. The 7mm PRC might have a slight advantage in ammunition prices due to its growing popularity. The cost of the ammunition can accumulate substantially over time. The higher the price of the ammunition, the higher the running cost of the sport.
Barrel Life and Its Implications
The 28 Nosler, due to its large powder capacity and higher pressures, tends to have a shorter barrel life than the 7mm PRC. Barrel life is a factor in determining the long-term cost of ownership. The more efficiently a cartridge burns powder, the longer the barrel will last. The 7mm PRC’s more efficient design often results in longer barrel life.
