An emergency order was made to manufacture quantities of ammunition that matched the external ballistics of the earlier M1906 cartridge as soon as possible.

This variant had the designation ML-20S . The muzzle velocity and external ballistics were identical to the original towed ML-20 gun.
14.
Use of ballistics tables or ballistics software based on the G1 drag model, introduced in 1881, are the most common method used to work with external ballistics.

The PSO-1 features a reticle with " floating " elements designed for use in range estimation and bullet drop and drift compensation ( see external ballistics ).
16.
A new and increasingly popular rimfire, the frangible hollow point bullets ( often manufactured with plastic " ballistic tips " that improve the bullet's external ballistics ).

However, external ballistics is also concerned with the free-flight of rockets and other projectiles, such as shells, rocket-assisted projectiles, balls, arrows etc.

This leaves the projectile traveling at high velocity with a smaller cross-sectional area and reduced aerodynamic drag during the flight to the target ( see external ballistics and terminal ballistics ).
20.
Other bullets in use by militaries are quite back heavy, due to a long, sharp point created in an attempt to get the maximum ballistic coefficient ( see external ballistics ).
