300 PRC

New drawing Coming

Introduced in 2018, the 300 Precision Rifle Cartridge (PRC) has one significant reason for existence: as with a few other modern chamberings, it uses cartridge and chamber specifications and tolerances appropriate to the Space Age, instead of the horse-and-buggy era. This is no small matter.

As such, rifles chambered for this cartridge can deliver impressive accuracy with good factory ammo and do so far more easily and often than can be expected with older chamberings having much wider specification tolerances.

Ballistically, the 300 PRC has a significant edge over the 300 Win Mag because it is loaded to about 5% higher pressure and maximum overall length is about 0.33-inch greater, which results in significantly greater usable case capacity.


Velocity advantage of the PRC when using best loads in each round is about 60 fps with typical hunting bullets. But, as noted, it is the intrinsic accuracy edge and the ease of achieving such accuracy that matter most.

The PRC also has a longer neck, perhaps long enough to improve barrel life. This will certainly matter to those who have spent time, energy, and money developing accuracy loads for their hunting rifle. If a factory magnum-class 30-caliber rifle were of interest to me, this would likely be my choice among many options.


The text associated with the cartridge description reflects opinions and conclusions of the author, M.L. (Mic) McPherson. Lee Precision and its employees do not necessarily either agree or disagree with any of his comments. We present these with due deference to his recognized expertise in the firearms field. His acumen extends to handloading and all aspects of ballistics - internal, external, and terminal.
