The need for a LEVEL.
The concept is one that is difficult to understand. With the tremendous speed, FPS, we have available to us, Understanding the pull of gravity on a projectile
is difficult to comprehend.
To simplify the problem, it depends on whether you are satisfied with hitting
the side of a barn with a 10 foot group or grouping your shots on a pin head.
The range I shoot at is as good and well maintained as any. However I checked the cement deck with a 10 foot level and found it to be on about
a 12 degree slope. You can't tell it by looking, It looks level and square.
Sitting at a shooting bench I got to wondering why the level on my rifle was about half a bubble off when I set up. Therefore the level check.
The Compound Olympic Archer shooting at 90 meters is not concerned with
hitting a 9 inch gold, his goal is to hit the three inch X ring in the gold at 90 meters. You can bet hard money there is a level on his bow.
To hit a 3x4 foot target at 1000 yards with todays rifle and aiming systems
is relatively easy. I hit one twice last week and I turned 80 in February.
But to shoot a group the size of the one Len shot compared with a dollar
bill is another thing.
It's a BIG thing, it's the Earth's GRAVITY pulling the projectile back to center.
The Old time Bow Hunters were always saying "lean the upper limb into the
hill." How much? well that's the lesson you learn with time.
