I know several guys that shoot that far and are great shots but say they only do it with no wind.To me I have no problem at 45 yards and pratice it alot.I feel that is the key to the distance is if the shot is practiced enough and you feel confident in the shot and nothing in between you and the shot like a tree limb or fence because small things such as that are hard to see at longer distances and definatly leed to wounded deer.
I know most people hunt in areas they hunt all the time but branches do jump in the way on purpose .
No matter what it still comes down to if you feel comfortable with the shot and the distance.
