I recently did a shopping comparison of 6.5 prc, 7mm PRC, and 300 PRC. While 6.5 will certainly kill all intended western game just fine within its limits, I like a bit more knock down power but was not sure I want the extra recoil of 300 prc since they are designed only for heavy bullet weights and long range shooting. I don't shoot animals past 600 yds so 7mm PRC fit the bill for me. Actually in typically barrel lengths the 180 gr bullet 7mm PRC energy is not too far off from 300 PRC at 1000 yds in one review I read. I can't recall the bullet exactly but both are high BC bullets. I chose 7mm PRC but with short 18 inch barrel to be used with a suppressor and good to go out to 700 yds according to the guy at Gunwerks. Hill country you tube video was where I found a lot of useful data.
