.300 Precision Rifle Cartridge

The .300 Precision Rifle Cartridge, commonly known as the .300 PRC, is a relatively new entrant in the world of long-range precision shooting. Developed and introduced by Hornady in 2018, this cartridge was designed to optimize the synergy between high ballistic coefficient bullets and modern rifle actions. Its genesis is rooted in the desire to deliver superior performance over traditional magnum cartridges, such as the .300 Winchester Magnum and .300 Norma Magnum, while also complying with the dimensional constraints of standard long-action rifles. The .300 PRC is based on a modified .375 Ruger case, necked down to accept .30 caliber bullets, and engineered to provide optimal case capacity, streamlined feeding, and efficient powder burn. The cartridge quickly gained favor with both competitive shooters and military marksmen seeking high precision and repeatable accuracy at extreme distances.

In terms of applications, the .300 PRC was conceived for long-range precision shooting, and it excels in this domain. Its case design allows the use of long, heavy-for-caliber bullets that retain velocity and resist wind drift better than many predecessors. Precision rifle competitors, law enforcement sharpshooters, and military snipers have all recognized the .300 PRC’s ability to deliver consistent performance out to—and well beyond—1,500 yards. The cartridge is also popular among civilian enthusiasts who participate in PRS (Precision Rifle Series) matches or who are looking for a high-performance option for recreational long-range shooting. Reloaders especially appreciate the .300 PRC for its capacity to accommodate a wide range of powders and projectiles, making it a flexible and rewarding caliber for handloading.

For hunters, the .300 PRC is an excellent choice for pursuing large game at extended ranges. Its impressive combination of high muzzle velocity, heavy bullet weights, and excellent ballistic coefficients make it ideal for hunting elk, moose, and other large-bodied game in open country where long shots may be required. The cartridge’s flat trajectory and retained energy at distance ensure reliable terminal performance, even on thick-skinned targets. In North America, it is increasingly favored by guides and experienced hunters heading into the mountains or wide-open prairie. While it may be considered overkill for deer-sized game at typical hunting distances, the .300 PRC’s versatility gives reloaders and hunters the option to tailor loads for a variety of target species and scenarios.

Typical bullet weights for the .300 PRC range from 180 to 230 grains, with the most popular projectiles falling in the 212- to 225-grain range. These heavier bullets take full advantage of the cartridge’s generous case capacity and long throat, allowing for seating bullets with high sectional density and superior aerodynamic profile. Reloaders appreciate that the cartridge’s design allows them to experiment with different powder combinations and bullet seating depths, optimizing for both velocity and precision. The .300 PRC operates at a maximum average pressure of 65,000 psi, contributing to its ability to launch heavy bullets at impressive velocities—often exceeding 2,900 feet per second with 225-grain projectiles. The caliber’s efficient case design and modern chamber specifications promote consistent neck tension and concentricity, two key attributes sought by serious reloaders aiming for sub-MOA accuracy.

Overall, the .300 PRC stands out as a modern, versatile cartridge for reloaders who demand precision, flexibility, and downrange performance. Its thoughtful engineering, excellent ballistic capabilities, and support from major ammunition and component manufacturers have cemented its place among the elite .30 caliber magnums. Whether your goal is competition, hunting, or pushing the limits of long-range shooting, the .300 PRC provides a compelling platform for those who relish customizing their ammunition for the ultimate in performance and accuracy.
