Thank-you for all your input, we took your advice and used a heavier shot. My daughter used a Winchester 243 95gr. Ballistic Silvertip cartridge, she shot two whitetails this year at 110 yards. I was surprised the exit wound was 1½” in diameter. Also willhunt4food is correct with the statement “The main thing is to make sure your daughter has fired it enough to be comfortable and accurate.” Last year at NRA camp she took first in group and seconded in overall out of 95 kids. She was 11 at that time.
