Weight, velocity, and shape of the bullet.
Factors include the angle at which it is fired, the speed of the projectile, its shape (ballistic coefficient) the air pressure and humidity.

The maximum range of a projectile is the distance it travels horizontally before hitting the ground. It is influenced by factors such as initial velocity, launch angle, and air resistance. In a vacuum, the maximum range is achieved at a launch angle of 45 degrees.
The range of projectile is maximum when the angle of projection is 45 Degrees.
The first factors are: Speed, weight, and shape of the projectile. Speed will be determined by the powder charge used to drive the bullet, and the length of the barrel. Elevation angle (the angle at which the barrel points upward) will then increase or decrease the range based on the first three factors. For most firearms the optimal elevation angle is between 30 and 40 degrees for maximum range. Other lesser factors include the weather (wind, humidity, temperature) and altitude. Even the Coriolis Effect can play a small factor.
The maximum height of a projectile depends on its initial velocity and launch angle. In ideal conditions, the maximum height occurs when the launch angle is 45 degrees, reaching a height equal to half the maximum range of the projectile.
The half maximum range of a projectile is launched at an angle of 15 degree
Ignoring the effects of wind and air-resistance in general, maximum projectile range results when the projectile is launched/fired in a direction 45 degrees above the horizontal.
The launch angle and initial speed of a projectile are both factors that determine the range and height of the projectile. A higher launch angle with the same initial speed will typically result in a longer range but lower maximum height. Conversely, a lower launch angle with the same initial speed will result in a shorter range but a higher maximum height.
The horizontal component of a projectile's velocity doesn't change, until the projectile hits somethingor falls to the ground.The vertical component of a projectile's velocity becomes [9.8 meters per second downward] greatereach second. At the maximum height of its trajectory, the projectile's velocity is zero. That's the pointwhere the velocity transitions from upward to downward.
