What rifle would you recommend for a 10 year old grandson for deer. All he has ever shot is a 22 when we go squirrel hunting. He is a bit shorter than the average 10 year old but bulky and filled out well. I am not an avid deer hunter and all that I have is a 30-30 and I have only killed a few deer. Mostly I am a fully addicted squirrel hunter with a feist dog. I want something that will not kick him bad and the deer range will be within 100 yards. A recommendation on a rifle and cartridge load would be appreciated. Thanks my fellow GON friends.....
