Being a first time bowhunter, I am curious to see what you feel is the "average" distance for a good shot on a whitetail.

I've done most of my practice in the 20-25 yard range shooting 3 to 5inch groups. I have gone out as far as 35yds shooting 5 to 8inch groups. Here is a group, of 4, I shot this evening from 25yards. This group is about 2 to 3 inches. Each group of 2 is about an inch apart.
