If Atticus is such a good shot, why doesn't he hunt, according to Miss Maudie?

From the text:

“Maybe I can tell you,” said Miss Maudie. “If your father’s anything, he’s civilized in his heart. Marksmanship’s a gift of God, a talent—oh, you have to practice to make it perfect, but shootin’s different from playing the piano or the like. I think maybe he put his gun down when he realized that God had given him an unfair advantage over most living things. I guess he decided he wouldn’t shoot till he had to, and he had to today.”
