It depends on what kind of country you are hunting in along if you are using a stand or not. I restrict my shots to 30 yards or less. But then I also will spot and stalk to within that distance or use a ground blind in heavy cover for deer and elk. The shots that I have taken have been anywhere from 5 yards to just over my 30 yard limit.
i try to stay within 40 yards.thats my comfert zone no need to make a bad shot and wound a animal. but then theres gyes who have bow hunted for a long time that can make 40+ yard shots. arrows are hard to find when they go to far and there too expensive to loose.
Really has to be up to you. You are the only one that knows your ability to make a clean kill shot. Practice, practice, practice! Don't be afraid to push your limits while practicing, really helps with accuracy and a better confidence at closer ranges. Starting out I didn't feel comfortable shooting at an animal over 20 yds. Now I feel confident to 40, and won't attempt anything much past that. I can make shots past 40, but too many variables the further out you get.
As I sit and glass, which is common for hunters out west, I have sort of quickly discovered something I never learned when I was younger.
In my youth I had enthusiasm and spirit. In my middle to advancing years I have creaky knees, arthritis, and I tire more easily than I used to. Where I used to sit on the cold hard ground I now look for that soft spot to sooth my tired muscles. That leads me to my tip.
Carry your soft spot with you!
In my pack I carry an air filled, ultralight, camping pad....
