The 7-08 is definitely a great caliber. This is what I bought my boys and I believe we have three laying around the house. I think with all things being equal you could say there is little difference between the .270 and the 7-08 but I believe your can tweek the .270 round to reach out and do a few things the 7-08 can't do or at least I don't feel comfortable doing with the 7-08.
I was deer hunting today over some cotton land that is being destroyed by deer. Today was the third try at planting this little nook that goes into the woods. At $700 a bag for seed the deer are causing a real problem and with the monster mosquitoes this last storm brought in I wasn't about to sit in the woods where I would be sucked dry of my blood so I set up in the middle of some new ground and my shots were pushing 600 yards at the furthest points.
