This is awesome! Congratulations are in order to both of you. My daughter started shooting with my wife and I when she was 6. She shoots rifles and pistols, and also handloads with me. She is 9 now and shot her first deer this year. I am right with you on the 243 Win. Mine uses a Model 110 and we use 95 gr Noslers BTs at 2800 fps. It is a mid range load that does very well. Once again, congratulations. Let us know of your families future successes and when your youngest gets started.
