You will have to reload for your 6.5-06 obviously.
I do reload, and my choice would be 6.5-06 for just a hunting rifle. However, I just went form an '06 to a 6.5x55. Why? Barrel life. I shoot a few thousand rounds a year and the 6.5-06 wouldn't cut it in barrel life.
Remeber though, you can always down load a cartridge, but you cannot push it past the max. In other words, the 260 will only do so much....The 6.5-06 can do the same loaded mildly.
PS - This may have been already stated as I was not going to read through this whole thread.
