[QUOTE="entoptics, post: 2825578, member: 104268"] I'm of the opinion that 6.5 PRC in a short barrel might be marginal on elk past 500 yards in terms of retained energy. 308/7-08 will struggle to maintain >1900 fps at 500 yards, let alone 600 yards for your sheep scenario, so that really only leaves 300 WSM in your list. Have you considered 6.8 Western or 270 WSM? Not a ton of factory ammo available, but it's out there. Performance should be near enough ideal for your parameters, substantially less recoil than the 300WSM. @ 500 yards, standard atmosphere at 3000 ft elevation (rough guess for 16"-18" bbl velocity by subtracting 200 fps from 24" load data)... 6.5 PRC, 143 ELDX, MV 2750 fps = 2100 fps, 1400 ftlbs @ 500 yards 308, 178 ELDX, MV 2500 fps = 1850 fps, 1350 ftlbs @ 500 yds 7-08, 162 ELDX, MV 2550 fps = 1900 fps, 1300 ftlbs @ 500 yds 270 WSM / 6.8 West, 145 ELDX, MV 2900 fps = 2150 fps, 1500 ftlbs @ 500 yds 7 SAUM would be also be a good choice ballistically, but I think factory ammo selection is about zero...
