I'll be taking my Granddaughter deer hunting to hopefully shoot her first deer this season. She is 10 years old and shooting my AR15 well. I plan on using 64gr sp. She can put 5 of them in less than an inch at 50 yds. That will be the approx. feeder distance where she will hunt. My question is, what is the best shot placement for her. Double lung shot just behind the shoulder? Or right on the point of the shoulder to brake some bone or high shoulder (cns)
