go with the 7mm mag. It's a little big for whitetails but if you ever want to hunt elk, bear or other larger game your all set. Its better to have to much gun than not enough. I had a 270 for 10 years then purchased the rem. 7mm mag. and love it. Ohh make sure you wear ear plugs when you shoot the 7mm. TRUST ME, MY EAR STILL RINGS 3 YEARS LATTER
