Consider that most 6.5mm Creedmoor factory ammo uses fast expanding plastic tipped cup core bullets.
HPBTs like the Scenar or VLD just work better, in my opinion. In both the 6.5 CM and .270 Win.
I have killed couple critter with 140 berger vld in 6.5 cm but not enough to really have an opinion. However my cousin and his family have shot a bunch with 139 scenars in 6.5 cm/prc with outstanding results so think you are probably right.
