OK to Chime in on the 270 -280-06 debate.
All have there merrits all have their deductions.
after all we are talking the difference between .277, .284, and .308.
I also think 280 would have had a better start if Remington quit renaming it!
First it was 7-06 then 7mm Express, then finally 280.
I also think they should have done the 7mm's as a family and showed the versitillity of them but they came out with 4 7mms and they all do about the same thing. 7-08, 284, 280, and 7mm are all within 100-200 FPS of each other with a 140 grain and do exactly what the 30 cal does.
When a freind was looking at a 7mm Mag I always thought why get a 7 when a 300 will do so much more. After reading up on the 7mm Mag, one is now on my want list. but so is another 308 win and another 338WM.
But I have a different intended use for each of the new wants. I am guessing much like Lost Oki has uses for each of his 270, 06, and 35Wh.
