Get the 7/08. Shorter action, lighter weight, easy on the shoulder, easy to reload for. I bought a Remington 700 CDL in 7/08 several years ago and it gave me fits as far as accuracy goes. I finally had it bedded and a trigger job done and now its a .5 MOA shooter with handloaded 140 gr. Accubonds. I used it last year on my west Texas lease and took a good whitetail at 302 yards off the sticks. He never knew what hit him.
