I own a 6.5x284 and a 7mm PRC and used to have a .284. All three are really useful cartridges and provide a good level of accuracy when handloaded. The 7mm PRC is really easy to load for and the factory ammo shoots pretty well (both the match and hunting loads, haven't shot the monos yet). Components for the PRC are readily available. This would probably be a good choice for a starter in LRH.
