I opted for 51-60. I practice out to 60-70 all summer long and am very confident in my abilities. The farthest I have shot a deer was 48 yards while I was on the ground walking back to the truck. With todays bows with the speed and sound these shots are not a problem. Can the animal move? Sure. They can also move at 20 yards. In my experiance the deer never hear the shot if they are beyond 30 yards thus dont react as they do when closer. So if you dont feel confident in shooting beyond 30 yards, dont scorn those that do.
