If you want a Rem 700 in .308, and you would consider a heavy 24 inch barrel, look at the Rem 700SS Milspec model with 5R rifling, the same rifling pattern used in the barrels of the M24 (Army) and M40 (USMC) sniper versions of the Rem 700. The 5R Rem 700 is produced in limited numbers, but can be obtained from a few dealers on the web. You can read about it here:

I bought mine by phone from Jensen Arms in Loveland, CO.
http://www.jensenarms.com/I put a Badger Ordnance 20 MOA canted Picatinny rail, Burris Xtreme rings and a Leupold 40mm 4.5-14 power target scope on it and used it for a precision rifle class in Princeton, MN in April and to shoot NRA F-Class at Elk River Sportsmans Club this past spring and summer. I chose this rifle because I don't yet reload and have to use commercial match ammo and this rifle loves the overall length typical of factory ammo. I have had excellent results with Federal GMM 168 gr and Black Hills Red Box Match 168 gr. With the Black Hills I have one three shot group at 100 yds of just over .125 inches. On the 100 yd range It consistently shoots under .5 MOA for me and I am a relatively new to competitive rifle shooting. The trigger is okay and easily adjustable for pull weight, but this winter I am going to put a Jewell in it.
Because of its weight, this is not a rifle suitable to haul up a mountain or for long hikes. But in a deer stand in the open or for other long range shooting, you can't beat the performance for the price.
