Muscle Memory:
The key to becoming a great shooter.  Your body and mind remember the last shot that you took.  The more bad habits you build, the harder it is to become a great shooter.  At the same time, the more correct fundamentals you practice, the more efficient and closer you will become each day to a great shooter.  Few shooters have the ability to overcome flawed fundamentals.
Below are break downs the fundamentals of a great shooter:

Feet and Foundation:
Any shooter needs to start with a great foundation.  Have your feet shoulder-width either apart and parallel or one foot (your shooting side foot) in front of the other.

Shot Ready:
Being ready to shoot is a vital part of being a great shooter.  First, a great shooter must have their knees bent for power and balance.  Then a great shooter has their wrist cocked in preparation to receive the basketball.  Eyes should be on the target once the ball is received.  Lastly, a great shooter has their elbow in close to the body while he is preparing to shoot.

Taking the Shot:
Once the ball has been received, the following steps should be taken.  First, find the target with your eyes.  Then start the ball in the shooting pocket (about chest level on your dominant hand side) and raise the ball in one motion thru the shooting shaft.  Once the ball is released, pronate your fingers towards the target.  Keep your eyes on the target, not the ball.  Lastly, do not fade away from the target, but instead follow your shot.

PRACTICE, PRACTICE, PRACTICE:
The last major part of becoming a great shooter is practice.  The more you practice at game speed, the closer you become to being a great shooter on game day.  Work on all aspects of shooting: Off the dribble, stationary, off the screen, mid range shots, three-point shots, backboard shots, foul shots, off-rhythm shots, and float shots.  There is a lot of work to be done, but the reward will be you achieving great shooter status.

There is no magic pill to becoming a great shooter.  By adhering to the fundamentals of shooting above, becoming a great shooter can be attained through hard work and perfect practice.  Best of luck becoming the next great shooter!!
