I recently bought a 6.5 PRC Browning X-Bolt Pro which I have found to be very accurate, as in 7/8" 3 shot groups at 200 yards with Hornady ELD-X Precision Hunter factory ammo. 3 shot groups B/C the ammo is 'spensive.
It has the standard X-Bolt center feed polymer magazine which barely fits the SAMMI length round. A good and reliable magazine as I found with a previous 6.5 CM pro (that is now For Sale in the LRH Classifieds).
I went for the 6.5 PRC because I think that cartridge will become popular, especially in the western US and Canada. But hey, I could be wrong. Still it is a very good cartridge for all Nevada game including bull elk at 300 yards or less. And I wanted the lower weight of a short action rifle that the 6.5 PRC offered.
