[QUOTE="vancewalker007, post: 1802236, member: 66917"] I ran a few ballistic compares and the two are pretty close at 600 yards, in the 50ish inches range, 6.5 PRC edging the 280 AI by a few inches at 600, and a little on velocity and energy. But we are talking about 100ish fps and less than 100 ft lbs. I don't have a 280 AI to test but my 6 5 PRC can provide 1930 fps and 1290 ft lbs at a 1000 yards, at 3700 ft alt and 55 deg F. I've never reloaded for the 280 AI, so I don't know how easy it is to squeeze accuracy out of, but the 6.5 PRC is very easy to find sub 1/2 MOA loads for. The other advantage the 6.5 PRC has is fairly low recoil. I think either cartridge will do the job you have with the right build. [/QUOTE]
