A trajectory chart for all major brands of .223 ammunition is available using the GunData.org ballistic calculator. Choose the bullet calibre of .223 Remington and the bullet brand and variant from the drop-down menu, then click Calculate to produce a trajectory chart.
The GunData.org ballistic calculator can analyze two bullets simultaneously to produce a comparative trajectory chart. Site visitors can edit firearm-specific information, such as muzzle velocity, to improve the accuracy of the result. Advanced options allow inclusion of such data as zeroing distance, shooting angle, sight height over bore, wind angle and velocity, atmospheric conditions, and distance to target.
