I was looking to get my son new rifle. either the 6.5CM or 7-08. I already have 270 and 06, and didn't want 243 or 308
went to Sportsmans and there had to be 4 times more ammo of 6.5 vs 7-08 and some boxes half the price. Now, I do reload, but sometimes in a pinch or emergency... 7-08 just ins't there.

All of them do something better than the 30-06, but none of them do everything as well.
