Even Jack O'Connor said the .30/06 was better than the .270 so that leaves the .280 vs .'06.

The 280AI only equals the '06 velocities with like bullet weights, so doesn't that make the plain 280 a lesser option?

Then we have bullet weight range, 7mm Vs .308 caliber. We likely don't need either weight range but more choices means more options to find what your rifle likes.

With it easier than ever to find a bullet that fully penetrates most game, where do you draw the line with bullet weight needs per caliber?

Again, JO'C shot clear through a grizzly with a 180gn bullet in his .30/06 and declared no heavier bullet was required in the '06. Was he right?

Being younger and still knowing everything is terrific, until you meet an old guy with a battered rifle he's had a while and he pulls out a crumpled partly used blue box. Then you get to learn something you thought you'd already mastered. I hope everyone eventually meets the old guy.

When truth is ignored, it does not change an untruth from remaining a lie.
