Some cartridges in a certain caliber are far more effective than others, which is obviously true of the giant-killing 6.5 Creedmoor. Similarly, if your neighbor's brother-in-law's doctor had used the magical B-29 round, instead of some wannabe based on the tired old .30-06 case, the buck would have not only died right there, but the bullet would have flipped it on its back and performed the field dressing.
Several years ago I shot a small buck @ about 30 yards quartering away. At the shoot the deer did a 180 back flip and landed on its back, DRT. At the time I thought it odd, but now I know....
.30 out of a .308 case.
