2.5 moa? That is not asking for much.
I would be very dissapointed in a .308 that didn't shoot at least 1 moa. There are several good choices but I would recommend a Savage 10, a Remington 700, or a CZ 550. I am not sure of the current prices on those though. Another good option is the Stephens 200 which is basically a pre-accutrigger Savage. For the price they can be bought for, you could easily add an aftermarket trigger. I have a Timney in mine (pre accutrigger 110) and absolutely love it.
