It is a little unorthodox but I used a 140 gr. out of my 6.5 creedmoor to take an elk at 370 last year. the bullet performed very impressively... took out the heart and lungs went through the opposite shoulder blade and stopped just inside the skin on the far side. The elk dropped in mid stride. i was getting 3 inch 5 shot groups at 500. it has a decent bc as well.
