ABSTRACT
The factors of load, lag, gain, and lead all affect the outcome. Even for the skilled shooter, reducing mistakes depends upon the rapid and accurate calculation of all four factors. Design engineers
have long recognized the limitations of training programs and the extent to which highly skilled tasks can be mastered. Increasingly today our technologies assign more and more of such calculation to computers, whether those of military weaponry or those of organized work. It is also why hunters, when faced with the crafty fowl instead of clay pigeons, still prefer birdshot to bullets.
