Is 6.5 PRC a Short Action? Understanding Cartridge Cases and Action Lengths
The question of whether the 6.5 PRC (Precision Rifle Cartridge) fits a short action is a common one among rifle enthusiasts. The answer isn't a simple yes or no, and understanding the nuances requires delving into the specifics of cartridge dimensions and receiver design.
Understanding Action Length:
Before jumping into the 6.5 PRC, let's clarify what "short action" means. A rifle's action refers to the part of the firearm that houses the bolt, magazine, and firing mechanism. Action length is determined by the overall cartridge length, specifically the distance from the base of the cartridge case to the tip of the bullet. Short actions are designed to accommodate cartridges with shorter overall lengths, while long actions are built for longer cartridges. This directly impacts the space available within the receiver for the cartridge to cycle smoothly.
6.5 PRC Dimensions:
The 6.5 PRC boasts a relatively short overall length compared to some other popular magnum cartridges. This shorter length is a key design feature intended for improved balance and handling in hunting and long-range shooting applications.
The Complication: Variations in Receiver Design:
While the 6.5 PRC generally fits within a short action, there's an important caveat: manufacturer variations. Different manufacturers might have slightly different tolerances and designs for their short actions. Some might accommodate the 6.5 PRC perfectly, while others might require minor modifications or might not be compatible at all. This is particularly relevant for custom-built rifles where the action is selected specifically to match the desired cartridge.
Factors Influencing Compatibility:
-
Magazine Length: The magazine's capacity and design play a crucial role. A short action magazine specifically designed for the 6.5 PRC will work flawlessly. However, using a magazine not designed for this cartridge may limit capacity or cause feeding issues.
-
Bolt Throw: The bolt throw, the distance the bolt travels to eject and chamber a round, is indirectly affected by the action length. A short action bolt throw is typically shorter, contributing to quicker cycling and a more compact rifle design. The 6.5 PRC's dimensions generally align with the specifications for an optimal short-action bolt throw.
-
Headspace: Precise headspace is critical for safe and reliable functioning. An improperly set headspace can lead to dangerous malfunctions. Therefore, ensuring the chosen short action has the correct headspace for the 6.5 PRC is paramount, regardless of the manufacturer.
In Conclusion:
The 6.5 PRC generally works well with short actions, making it a popular choice for hunters and long-range shooters who value a compact and balanced firearm. However, it is imperative to verify compatibility with the specific rifle manufacturer and model you're considering to avoid potential issues with feeding, reliability, or safety. Always consult the manufacturer's specifications and potentially a qualified gunsmith for any questions concerning action length and cartridge compatibility.
