Are you planning for long range? If not, you'll gain nothing over a 25-06 BTDT. My 24" 6.5-06 shoots 120NBTs at 3150. My last 24" 25-06 shot the 115NBT slightly faster. There was no difference in the field at normal ranges.
Sleek long bullets is a different subject, but from what you're planning on shooting, I don't see a benefit.
Now, the 6.5-06 is definitely cooler
