I am only offering my opinion and I'm sure there will be many others. Best reach but lowest recoil category would belong to the various 6.5 mm .260 cal. class. Equal reach, more power but more recoil would be the .30 cal magnum class. Best B.C. and as good as anyone else reach class, but with a bit more recoil, the hot 7mm"s. My opinion, with unlimited resources, meaning you could buy whatever you wanted, I'd do this. For targets and hunting, I'd go 6.5-284, or .264 Win. Mag. for hunting at extreme ranges, 7mm Rem. Ultra mag. Hunting at extreme ranges and needing severe foot pounds of energy, .300 Rem. Ultra mag. If you need more than that, stay home, it isn't worth it.
