An arrow at 85 yards takes a long time to get to it's intended target. Think about it, how many times have you seen an animal stay still long enough at an extended range to draw your bow, settle your pin, and pull through your shot. Factor in your nerves and not being "warmed up" and you are really creating a situation for disaster (wounded game animal).I don't think that the harvest of an animal is worth the gamble of wounding one because the animals we hunt for deserveour highest respects. Sure some of us may be able to shoot out to 100 yards with an arrow consistently but that's at a stationary object in a controlled, nerveless environment.
I would say that my maximum range would be 30 yards under ideal conditions at a game animal. This isn't saying that this is the limit on my ability because I consistently shoot 3 inch groups out to fifty yards with my broadheadsand can consistenly hit a pie plate out to 65 (don't ever shoot farther than that) but I am one of those people who only take shots that I will double lung the animal 100 out of 100 times. I've never lost an animal and I'm not trying to say I am better than anyone else but I am very particular with shot placement and I do pass up on a lot of "chip shots" that I probably could have made. To me, a lost animal is just not worth it. An opportunity to just watch a whitetail in it's natural environment is a trophy in itself to me and I thank God for it every day.
