Re: please help me with this.. its realy puzzling me
Are you kidding with this question?
If not:
The bullet which exits the barrel of the rifle will change its place of impact depending on several factors, range, bullet weight, type, powder charge, wind, tempature.... do you get where i am going with this?
the scope allows you to "move the bullet to where you want it to strike" in a most simplistic way of putting things.
if you take your rifle to the range and "sight it in" at 100 yards, you now have a starting point for most ballistic cards, or with a chronograph, you can make your own.
