The long range rifle has been around since the 19th century, a short 100 years after Daniel Bernoulli published his book, Hydrodynamica, on the relationship between pressure and potential energy (or speed) of a fluid. The jist of his principle relates an increase in speed of a fluid to a decrease in pressure. Using this with the venturi effect that states the velocity of a fluid increases as the cross sectional area decreases provides the key to projectile ballistics.
