I have an old .270 that I am really wanting to make into a serious longrange rifle. Since the rifle is already a long action, is there any reason not to go with the .264? Or are the other rounds more inherently accurate? Could aftermarket barrel choice be a factor in this as well?
If you are interested in .264s, look into the 6.5-06 or the Ackley Improved version. This is an extremely accurate cartridge and the only thing that would need modified is your barrel of course. The velcity of this round falls right in between the .260 and .264 Winchester and would be a great choice. The 6.5 Sherman is also another option, performance is like the 6.5-06 Ackley. If you're not dead set on a 6.5 you could look at a .270 Sherman or Ackley. Like MudRunner suggested, the .280 Ackley is another great option. You have a ton of choices out there, just have to narrow down what you can get components for, what will be easiest to work with what you have, and what you want the cartridge to do.

I have always wondered why there is no factory long action 6.5 rounds, like a standardized 6.5-06 easily available.
.264 WinMag is a magnum long action caliber. The .260 Rem is a short-action, but uses the standard (.308/.30-06/.270) bolt face.
You could build a 6.5-284, a 6.5 Sherman, or a .260 Ackley Improved on your long action. Which would make a nice hunting rifle, because you could load those long Berger 130 & 140 Hybrids all the way out to the lands, and still have that extra magazine length to shoot it as a repeater and hold a full magazine. Which is where using a short action reciever kind of cripples you, because they have a short magazine box and can't load the 6.5's to their full potential with the long & heavy 6.5 bullets.
I recommend using the long action for any of those calibers. It will be added convenience, and I think you'll like having that extra magazine room for loading them long.

The only problem is the fact that I would rather not start handloading yet, as i am just about to start college, and this is probably a project that will happen in a few years from now anyway. I picked a bad time to start wanting to shoot longrange didn't I
The new king of the hill in 6.5mm as far as commercially available stuff goes is the 26 Nosler. (Check out Nosler's website.) Since a gunsmith would have to install the barrel anyway it wouldn't take much to open up the bolt face and fix up the magazine to hold the fatter rounds which are the same COAL as the 30-06. Disclaimer: It is anticipated that this will be a barrel burner - but as has been said on here before, barrels are like tires, when they wear out just get a new one.
