The 6.5-284 has been an unattractive caliber to me because of big powder charges and short barrel life (reportedly ~ 1200 rounds or a bit more) and I fear the 6.5-06 might suffer the same thing. That's why for me if it was a 6.5 it would be either a 260/260AI or a larger caliber such as 7mm08/284 win/280/280AI with straight 284 Win being my favorite...
Read about the straight 284 over at 6mmbr.com they are very impressed by it..
