Through intense experiments we learned that there is in fact bullet drop, but first, there is bullet rise. Anything below 75 meters you need to aim slightly below your target, though anything closer than 30-40 meters I agree to aim directly at them. Only at about 80-100 yards do you actually aim directly dead center and slightly higher as your range increases. Using this method we managed about 70% hits using muskets at a range of 75-150 yards. Sounds wild, but it works.
