Out to 600 yards a 308 and a 6.5 cm are almost identical with an SST bullet of similar weight according to my ballistic calculators. 1000ftlbs And 1800ish fps. Which is the slowest speed recommended by most hunting bullets. Thats on the slim side of suitable for an elk. Everytime i see arguments on here about ballistics its always a high bc bullet lower weight vs a low bc heavier bullet. 7mm vs 300win, 308 vs 6.5cm. The 308 has better ballistics than a 6.5 creedmoor if you compare two bullets of the same weight. If you compare a lighter bullet from a creedmoor to a heavier bullet from a 308 obviously the lighter bullet will have less drop. Whomever posted the creedmoor has better ballistics at 600 yards are using a different calculator than i am. Ive checked 2-3 different ones. I dont shoot 308 or a 6.5cm. These pics are a 6.5cm 140gr sst vs 308 150gr sst. As close as can get to same weight.
