The world of long-range hunting and shooting is constantly evolving, with new cartridges vying for dominance. Two cartridges that have recently captured the attention of enthusiasts are the 7mm PRC (Precision Rifle Cartridge) and the 28 Nosler. Both offer impressive ballistic performance, but choosing between them requires a careful consideration of their strengths and weaknesses. This in-depth comparison will help you decide which cartridge best suits your needs.
Ballistic Performance: A Head-to-Head Comparison
Both the 7mm PRC and 28 Nosler are designed for long-range accuracy and power, but their performance characteristics differ slightly. Let's analyze key metrics:
Velocity and Energy
| Cartridge | Bullet Weight (gr) | Muzzle Velocity (fps) | Muzzle Energy (ft-lbs) |
|---|---|---|---|
| 7mm PRC | 160 | 2950 | 3200 |
| 7mm PRC | 175 | 2850 | 3400 |
| 28 Nosler | 160 | 3100 | 3500 |
| 28 Nosler | 175 | 3000 | 3750 |
(Note: These are approximate figures and can vary based on barrel length, powder type, and other factors.) As you can see, the 28 Nosler generally boasts higher muzzle velocity and energy, particularly with heavier bullets. This translates to a flatter trajectory and more retained energy at longer ranges.
Trajectory and External Ballistics
The higher velocity of the 28 Nosler results in a flatter trajectory. This means less bullet drop and wind drift at extended distances, making it easier to compensate for environmental factors. The 7mm PRC, while not as extreme, still offers excellent trajectory for a 7mm caliber. The difference becomes more pronounced at ranges beyond 600 yards.

Recoil
The increased power of the 28 Nosler comes at the cost of higher recoil. This is something to consider, especially for shooters who are recoil-sensitive or new to larger cartridges. The 7mm PRC offers a more manageable recoil impulse.
Cartridge Case Capacity and Design
The 28 Nosler features a significantly larger case capacity than the 7mm PRC. This translates to greater powder capacity and consequently, higher velocities. The 7mm PRC, while smaller, is still a substantial cartridge capable of impressive performance. The design of both cartridges is optimized for efficient powder burning and consistent accuracy.
Practical Considerations for Hunters and Shooters
The choice between the 7mm PRC and 28 Nosler depends heavily on your specific needs and priorities.
Hunting Applications
-
7mm PRC: Excellent for a wide range of game, from deer and antelope to larger animals like elk and mule deer. Its manageable recoil makes it suitable for hunters who prefer a less punishing shooting experience.
-
28 Nosler: Ideal for long-range hunting of larger game. Its superior ballistic performance extends effective shooting range, enabling precise shots on challenging targets. However, the increased recoil might be a factor for hunters who prefer a less punishing experience.
Long-Range Shooting Competitions
Both cartridges excel in long-range shooting competitions. The 28 Nosler’s higher velocity gives it a slight edge in terms of reaching extreme ranges. The 7mm PRC is an excellent competitor, offering a balance between accuracy, velocity, and recoil management.
Rifle Availability and Cost
The availability of rifles chambered in both cartridges is continually expanding, but the 28 Nosler might have a slightly smaller selection currently. The cost of both cartridges and the associated ammunition will be comparable, although factors such as availability and demand will affect price.
Conclusion: Choosing the Right Cartridge
There is no single "better" cartridge; the optimal choice depends entirely on your priorities:
-
Choose the 7mm PRC if: You prioritize manageable recoil, all-around versatility, and a wider range of available rifles. It’s an excellent choice for both hunting and long-range shooting, offering exceptional accuracy.
-
Choose the 28 Nosler if: You require maximum ballistic performance at extreme ranges and are not as concerned about recoil. The 28 Nosler provides a significant advantage in long-range situations, pushing the boundaries of effective shooting distance.
Careful consideration of your individual needs and shooting style is crucial before selecting between these exceptional cartridges. Remember to research available rifles, ammunition costs, and your personal comfort level with recoil before making your final decision.
