I agree - we had just the 1 rifle and since it was Noah's license he got to carry it. Notice the USGI sling :-).
We had been sitting high up a hillside resting and waiting for some deer to cross a clearing directly below us (we were upwind). We finally got impatient, and started working our way down staying on the treeline when we spooked 2 doe. They crossed the open area and Noah took off after them. Once they hit the trees on the other side of the open area, they both stopped and turned to look at Noah. He dropped into a modified sitting position (forgot to sling up) and took the shot. He aimed for the heart, and hit the spine. However, it dropped the deer in its tracks. I know he was very excited to be taking the shot, so I chalk it up to nerves. Hopefully next time he will take a bit more time to make sure of his shot placement and use the sling so thoughtfully attached to the rifle.
We were using a .308 Ruger Mark II also shooting TSX's by Hornady I think 168 gr, but don't know off the top of my head. Also, I am estimating his shot at about 100 yards
