Correct me if lm wrong but the balistic energy of a 6.5 creedmore is 1225 ft pound at 600yds. Probably good enough for deer and coyotes. But recommended energy for large and DG is 1500 ft pds of energy. 1000 yd would be good for shooting paper only.
not sure what your asking or showing ? but if i am at a 1000 yd. bench match i wanna just use my 6 BR this cartridge may have poorer ballistics but still will shoot as good or better groups at 1000 yards with no recoil.
Hence the 6.5 PRC for Long Range hunting.
Carries more energy further, if that’s what matters.
300 PRC, 28 Nosler, 30 Nosler,RUMs , the Bees etc. All get it done.
But if you really mean business out to 1200 ish it’s a
33 Nosler , RUM on up to the Lapua .
With recoil attenuation ( brake ) the Norma makes a lot of sense
Plenty of Energy downrange with those
