It seems from the other post that you've made you are new to high powered files. Many have mentioned the assortment of 7MM's. If you are new to rifles I wouldn't buy a 7 MM Remington Magnum as my starting point. The recoil is considered stout by some and may or may not be bothersome to you. If you are going to only hunt whitetail deer, mule deer, antelope, & similar size game I would go with the 7MM-08 or the 280 Remington. These are both 7MM in bore size and offer good performance. The 280 beats the 7MM-08 by about 100-150 fps with each bullet weight. Both of these calibers are available in rifles from Remington, Browning, & Ruger. There are other companies that offer these chamberings also. Both of these calibers are excellent for taking deer and they will not rattle your teeth when you fire them. It's much better to buy a gun that you can shoot alot and learn to shoot well than buying the biggest magnum made and not being able to hit the broad side of a barn.
