From this story on heraldnet.com:

Justin Ristine, 11, might be the best one-armed hunter around. If ability is judged by percentage of shots fired compared to deer taken, he's as good a hunter as there is, one arm or two. On his first hunting trip earlier this month, he fired one shot and bagged one deer. The buck died instantly. The Marysville boy was born with only one arm, his left.
