What is the supersonic range of the 300 PRC?

The .300 PRC (Precision Rifle Cartridge) can maintain supersonic speeds to nearly 2,000 yards under specific conditions.

Understanding the .300 PRC's Supersonic Performance

The ability of a bullet to remain supersonic is a critical factor for accuracy, particularly at extended ranges. As a bullet transitions from supersonic to subsonic speeds, it can experience instability, leading to unpredictable flight paths and reduced precision. The .300 PRC is specifically engineered to maintain high velocities over long distances, offering a level of performance unparalleled by many other .30-caliber cartridges.

Key Factors Influencing Supersonic Range

The impressive supersonic range of the .300 PRC is attributed to a combination of design choices and ammunition characteristics:

• Optimized Ammunition: Readily available factory ammunition, such as Hornady's 225-grain ELD-M bullets, are designed with high ballistic coefficients, minimizing drag and helping to preserve velocity.
• High Muzzle Velocity: These factory loads typically achieve a high muzzle velocity, pushing bullets at speeds around 2,880 feet per second (fps). This initial speed is crucial for extending the supersonic flight envelope.
• Elevation Considerations: In testing scenarios, such as at a 3,000-foot elevation, the .300 PRC has demonstrated its capability to remain supersonic to almost 2,000 yards. Higher elevations generally result in less dense air, which reduces drag and allows bullets to maintain supersonic speeds for longer distances compared to sea level.

Performance Overview

The .300 PRC stands out as a top-tier cartridge for long-range precision, whether for competitive shooting or hunting. Its design and optimized factory ammunition work in tandem to deliver consistent and predictable performance even at distances where many other cartridges struggle to maintain stability.

Here's a summary of the observed performance characteristics that contribute to its supersonic range:

This combination of a heavy, high-ballistic-coefficient bullet and significant muzzle velocity allows the .300 PRC to push the boundaries of .30-caliber performance, making it a highly effective choice for engagements requiring extreme long-range accuracy.
