Brutal attack you are right, it is splitting hairs on performance. However there is alot more to consider. I can buy 30-06 at any Wally World, or any MA & Pa corner store in rural NA, at a reasonable price. This is not the case with the 280. I know charts can be quoted, but the 284 dia. will not kill like the 308. Ask Craig Boddington or any other hunter(notice I said hunter not shooter), he will inform you about the additional killing power of the 308 caliber. Also if you ever want to resell your rifle, the 30-06 will be considerably more valuable. Just go ask any gun dealer. Again I only meant my remarks as an opinion, not to start an argument. I think if you want to bring out something new then it should have many advantages, and I just do not see any advantages gained by the 280. Now if you want to talk about a 7 WSM, I will agree whole heartedly with you. Tom.
Any hunter will tell you that dead is dead. It's simple physics. You have a projectile of a known
mass traveling at a known
velocity that generates
X energy.
Modern big game bullets all perform well enough to take any north american game regardless of diameter. Expansionand performance isn't dependent on bullet diameter. If anything, 7mm bullets are more efficient which translates into more retained energy hence the higher ballistic coefficient of most 7mm bullets.
If you feel that a .308 bullet will "kill better" than a 7mm bullet than post something to that effect.
Opinions are basically worthless without some kind of fact backing them up.
