The short answer is yes, the 7mm PRC (Precision Rifle Cartridge) requires a long action. This is crucial information for anyone considering building a custom rifle or purchasing a factory rifle chambered in this popular round. Let's delve deeper into why this is the case and what that means for shooters.
Understanding Cartridge Case Length and Action Types
Before we specifically address the 7mm PRC, it's important to understand the relationship between cartridge case length and the type of rifle action needed. Rifle actions are classified as short, long, or magnum, primarily based on the length of the cartridge they can accommodate. A longer cartridge requires a longer action to allow for complete chambering and reliable feeding.
- Short Actions: Designed for shorter cartridges like the .308 Winchester or 6.5 Creedmoor.
- Long Actions: Accommodate cartridges that are longer than those fitting in short actions, such as the 7mm Remington Magnum or the 7mm PRC.
- Magnum Actions: Generally handle the longest and most powerful cartridges, often those with a belted case.
Why the 7mm PRC Needs a Long Action
The 7mm PRC's relatively long case length necessitates a long action. This longer case allows for a larger powder capacity compared to shorter cartridges, contributing to the 7mm PRC's impressive ballistic performance. This longer case simply won't fit reliably into a short action receiver. Attempting to force it would lead to feeding and extraction problems, potential damage to the rifle, and potentially dangerous malfunctions.
Key Considerations for 7mm PRC Shooters
- Rifle Selection: When choosing a rifle for the 7mm PRC, ensure it's explicitly designed for a long action. This information is usually clearly stated by the manufacturer.
- Magazine Compatibility: Magazines must also be designed specifically for the long-action 7mm PRC. Using the wrong magazine can lead to the same feeding issues as using a short action.
- Custom Builds: If building a custom rifle, careful attention must be paid to the action length to ensure compatibility with the 7mm PRC. This requires careful selection of components that all function correctly together.
Beyond Action Type: Other 7mm PRC Characteristics
While the long-action requirement is crucial, it's just one aspect of the 7mm PRC's design. This cartridge is also known for:
- Excellent Ballistic Performance: The combination of its case capacity and projectile design results in impressive long-range accuracy and trajectory.
- Moderate Recoil: Compared to some other magnum cartridges, the 7mm PRC offers relatively manageable recoil, making it suitable for precision shooting.
- Growing Popularity: The 7mm PRC has quickly gained popularity among long-range shooters and hunters due to its performance and versatility.
Conclusion: Long Action is Essential for 7mm PRC
The 7mm PRC is undoubtedly a long-action cartridge. Ignoring this critical fact can lead to significant problems and frustration. By understanding the differences between short and long actions and ensuring compatibility, shooters can harness the full potential of this high-performance cartridge. Always consult the manufacturer's specifications to ensure compatibility before purchasing or building a 7mm PRC rifle.
