You would not go far wrong with either caliber, but I agree with Todd1700 on ammo availability, at least in my area. If ammo ever gets scarce you can order it online through Midway, www.midwayusa.com.

Even if you reload, you may find a few more bullet choices available to you in 7mm. I reload for 6.5x55, and while you can get anything you want off the internet, the local stores don't seem to carry much variety in 6.5mm bullets. No matter, just about any 140 grain 6.5 bullet is accurate and penetrates very well at even modest velocities.
