Abstract
An experimental study of the behaviour of a bullet(caliber 7.62mm Ball M2) at an oblique water entry has been performed. The entry speed is adjusted to a value of about 300m/s. The range of entry angles is from 24 to 27 degrees. It is shown that the bullet runs stably only when the bullet travels broadsiding with the nose-down and during this period the trajectory can be fitted by an ana-lytical expression. After this phase the cavity collapses near the lowest region of the bullet trajectory and then the bullet goes up.
