Personal ethos mostly. Similar to how some people only shoot traditional archery or handgun to push the odds in favor of the animal and require a great stalk. I also don't consider myself a very good shot at longer distances but can and will make 300 yard shots if I absolutely have to (only once in the last 10 years). I have found that if I keep my shots within 100 yards then my efficacy is vastly increased and I am far more confident and satisfied with the result. But, to each their own.
