Hornady 300 PRC, Department of Defense

It appears the U.S. Department of Defense is adding the all-new Hornady 300 PRC (Precision Rifle Cartridge) to its arsenal. Last week the DoD awarded Barrett a contract to provide an undisclosed number of MRAD rifle systems chambered in 300 PRC.

We at Tactical-Life heard rumors of multiple U.S. branches exploring the 300 PRC. This, however, is the first official confirmation.

Barrett said its MRAD design coupled with the 300 PRCĀ “offer an unbeatable system for long range effectiveness.”

What Is the Hornady 300 PRC?

Athlon Outdoors contributor Jay Langston got his hands on the Hornady 300 PRC at the 2018 Athlon Outdoors Rendezvous. To better understand it, we need to look at similar cartridges.

The 300 Norma Mag is a necked down .338 Norma Magnum case necked down to .308. The name 300 Norma Mag was established to differentiate it from the .308 Norma Magnum designed in 1960.

“Like the 300 Norma Mag, the 300 PRC cartridge is a non-belted magnum,” Langston said. “Instead of being based upon one of the century-old British dangerous game cartridges, the 300 PRC is based upon the unique and original .375 Ruger case. One of the advantages of the 300 PRC case is that its base measures .532; this is the same as the .300 Winchester Magnum.

“The 300 Norma Magnum cartridge base diameter is the same as a .338 Lapua Magnum and its parent case, the .416 Rigby,” Langston added. “Perhaps the great minds at SOCOM were wanting bolt face compatibility in their switch-barrel Precision Sniper Rifle (PSR) ensemble when they adopted the 300 Norma Magnum.”
