Is there any good reasons to build a rifle in .308 when you can build the same rifle in .260?

Below is a link to a relatively long thread that covers the topic pretty well.

Take a look through there and see if it doesn't answer all your questions.

Re: Caliber choices
I have shot a .308 for many years and finally got a .260 this january and put 750 rds through it already, I don't shoot my .308 anymore.

Re: Caliber choices
at long range the transition from super-sonic to sub-sonic plays hell on light rounds. the 308 or 30cal in my opinion handles the transonic transition better because of the stability of the higher weight.
if your going to be doing long range you have to take that in to count, but also the drag coefficient is less on the 260 so it will stay super longer but will be affected by the "acts of god" more

Cowboy,
The transition from sonic has little to do with caliber and everything to do with the specifics of the geometry of the projectile.
For instance I shoot a 30 cal 230 grain hybrid that doesn't transition to subsonic the best. There are many 30 cal bullets that transition well and other calibers but not because of their weight.
To the OP. For a match cartridge .264 cal/6.5mm will serve you well. 308's usually get better barrel life.
