I don't have any problem with that BobCo, but I would like to point out one thing about a deer's reaction time that keeps me from setting a hard number across the board for maximum range.

Say a guy shooting a selfbow at 160 fps and is more than comfortable at 20 yards on deer. An arrow from that bow would travel 20 yards in something like .38 second. From a compound shooting 280 fps, an arrow would go 35 yards in the same amount of time. If reaction time of a deer is constant, and shooting accuracy is equal, it would exactly the same shooting the compound at 35 yards on a deer as using the selfbow at 20.

There are simply too many variables in bows, arrows, broadheads and shooting skills, not to mention weather, lighting and the attitude of the animal (relaxed or alert), even the hunters confidence level at the time of the shot, for anyone to lay out a definitive maximum effective range across the board for all situations.

Each and every hunting shot is entirely unique and has to be judged on it's own.

I do think that very few people have the skill to even attempt a hunting shot, even with the most high tech bow, past 30 yards under hunting conditions.
