Too many variables to give an answer....animal position, alertness, what it it's doing etc. Also the terrain and surrounding cover for observing impact and subsequent followup on the shot? Wind? Time of day? Lighting conditions? I will say I practice out as far as 100 yards on the level and downhill shots on the mountain in the back yard. But I hunt within the the 5 fixed pins on my slider sight (0 - 60 yds). Would take a followup way out there if a wounded critter gave me a shot. I really like 20 to 40 yard shots. Under 20 and things can often fall apart. Over 40 becomes much more critical on a variety of fronts but still very doable.
Good luck to the original poster!
Yeah, A lot of good points here also.
The Equipment used, and then the Variable's of the Conditions, like you say, all enter in!
Practice, Practice, Practice!
Never a shortage, or excuse for not getting enough practice!
