another thing, we all know that when that deer does come, all of our heats start to pound like they are going to explode... being 20 yards from a deer with a bow, your heart would pound a ton more than if you were 100 yards away (or more) from a deer with a shotgun or rifle (at least thats how it is with me). if your heart is pound like crazy it is going to affect how accurate your shot is because it will be harder to hold your bow steady versus if your heart isnt pounding as much then it will be a lot easier to hold your gun steady. so i agree with all the people who say that you "think" you made a good broadside shot, when you really probably didnt.
my 2 cents.
