From Guns.com:

The 6.5 PRC has gained a respectable following since Hornady Mfg released it two years ago. Long-distance shooters and hunters desire the Precision Rifle Cartridge for the additional power it brings to its predecessor, the popular 6.5 Creedmoor. While still young, the 6.5 PRC is building on 6.5 Creedmoor’s reputation. Today, more than a dozen manufacturers and small custom shops make rifles chambered in 6.5 PRC.
