Our local non-profit outdoor club holds an annual free hunter saftey class. We had a student who is about 40" tall and will never see much more. He is a very nice young fellow and deserves to have a well fitted rifle. During our last class he would not shoot a 20 gauge shotgun because the fear of recoil. I was asked if I could build him a rifle for deer hunting. It will have to be short relativly light, and easy on the shoulder. All ATF rules apply for minimum lengths. I have a caliber in mind, he will be woods hunting so shots will most likely be under 100 yards. I'm thinking 6mm-222, loaded with 85 grain gameking hp. Any suggestions?
