I'm getting ready to buy my Grandkids a starter whitetail deer hunting rifle and I would like comments on which caliber to get. I have 5 Grandkids and I'm pretty sure at least 3 and maybe 4 of them will want to hunt deer, two girls and two boys. Because PA has a youth mentor season I want to get something that's not going to kick the snot out a 8 or 9 year old kid. I've never been a big fan of the 243 but it is on my list as well as the 6.5 creed and the 7-08.Any others?
