A .270 or 7mm-08 might be fine for me, but I'm thinking about something that I can use to get my kids familiar with centerfire rifles. Also, something I can use for practical purposes - whitetail deer hunting, though I'm looking at a range of about 250 years max.
I really like the 7mm-08 and 7x57 for deer size game
