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.
