The world of long-range shooting is filled with exciting cartridge options, and two that frequently top the conversation are the 7mm PRC (Precision Rifle Cartridge) and the 7mm SAUM (Short Action Ultra Magnum). Both offer impressive performance, but choosing between them requires a careful consideration of your specific needs and shooting style. This in-depth comparison will explore the key differences between the 7mm PRC and 7mm SAUM, helping you make an informed decision.
Ballistics and Performance: A Side-by-Side Comparison
Both cartridges are designed for long-range accuracy and deliver exceptional ballistic performance. However, they achieve this in different ways.
7mm PRC: The Balanced Contender
The 7mm PRC, developed by Hornady, is designed for use in short-action rifles. This makes it a versatile choice for hunters and competitive shooters alike. Its shorter case length contributes to a smoother, more manageable recoil compared to the SAUM.
| Characteristic | 7mm PRC | 7mm SAUM |
|---|---|---|
| Case Length | 2.30 inches | 2.67 inches |
| Typical Velocity (175gr) | 2,900-3,000 fps | 3,100-3,200 fps |
| Recoil | Moderate | More Significant |
| Action Type | Short Action | Long Action |
| Barrel Life | Generally longer due to lower pressure | Potentially shorter due to higher pressure |
| Cost per round | Generally lower | Generally higher |
Data Source: Average values compiled from manufacturer specifications and various ballistic calculators. Actual velocities may vary depending on barrel length, powder type, and other factors.
7mm SAUM: The Powerhouse
The 7mm SAUM, a product of its Remington parentage, packs significantly more power than the 7mm PRC. Its longer case allows for a larger powder capacity, resulting in higher velocities and flatter trajectories at longer ranges. This increased velocity comes at a cost, however – noticeable recoil and potentially reduced barrel life.
Trajectory and External Ballistics
The following chart offers a simplified trajectory comparison using hypothetical 175 grain projectiles. Actual performance will vary based on specific ammunition. Notice the flatter trajectory of the 7mm SAUM at extended ranges.
| Range (yards) | 7mm PRC Drop (inches) | 7mm SAUM Drop (inches) |
|---|---|---|
| 100 | 4 | 3 |
| 300 | 20 | 15 |
| 500 | 55 | 35 |
| 800 | 140 | 90 |
| 1000 | 220 | 140 |

Rifle Selection and Practical Considerations
The cartridge choice dictates the type of rifle needed. The 7mm PRC works with short-action rifles, making it lighter and easier to handle for extended periods. The 7mm SAUM requires a long-action rifle, adding a little weight but providing the necessary case length.
Recoil Management: The significant difference in recoil should be a major consideration. 7mm SAUM's recoil can fatigue shooters faster during long practice sessions or hunts.
Cost Analysis
Ammunition and component costs typically favor the 7mm PRC. Brass, bullets, and factory loads generally come at a lower price point than their 7mm SAUM counterparts. This is a significant factor for high-volume shooters.
Which Cartridge Is Right For You?
The best choice depends on your priorities.
Choose the 7mm PRC if:
- You prioritize moderate recoil and ease of handling.
- You prefer a more budget-friendly option in terms of ammunition.
- You need compatibility with a short-action rifle.
- You're primarily shooting at shorter to medium ranges.
Choose the 7mm SAUM if:
- Extreme long-range performance and flat trajectory are paramount.
- You're comfortable with significantly higher recoil.
- You already have a long-action rifle or are willing to invest in one.
- You prioritize reaching the furthest possible distances.
Both the 7mm PRC and 7mm SAUM represent excellent choices in the world of long-range shooting. By carefully considering the factors outlined above, you can select the cartridge that best suits your individual needs and shooting style. Remember to always practice safe gun handling and follow all applicable regulations.
