6. factor in that the .270 has 10 % more cross-sectional area than the 6.5 for a bigger wound channel


Terminal ballistics often does seem to get left out of these sorts of discussions. It's one things to get a bullet to the target. What happens when it arrives? It may be generally true that a heavy-for-caliber bullet will have better external ballistics than a lighter bullet, all other factors being the same. But it's fallacy to believe a heavier bullet will penetrate further or perform better then it reaches the animal.
