I'm looking at purchasing a gun in the near future for my kid (they are to be born later this month) and mainly because Daddy has a good excuse to go buy another gun now. I would like to get something that is mild enough they can use when the start hunting, but also be good for when they get older. I would prefer a short action as I love my 223, but I use a 270 for deer. I've have great results with it, but from going from the 223 to 270 sometimes I don't always work the bolt quite far enough to reload. I've compared data on 243, 6.5, 7mm-08, 308 and even the 350 legend. We own a farm and for the most part I'd say that's where the hunting will be done unless they branch out. We have only small patches of woods with large fields. Shots will more than likely be anywhere from 25-300 yards. Any reason why 1 caliber would be better than the other?
