Survey of The Relationship Between Firing Angle and Distance of Heavy Rifles

This paper presents the results of a study on the relationship between firing angle and range when firing 12.7mm and 14.5mm heavy rifles under the same weather conditions. Relevant information includes aiming angle, firing angle, bullet trajectory height, range, and the lethal kinetic energy of the projectile. Using specialized software to calculate the external launch algorithm, the authors calculated the range for the 12.7mm and 14.5mm rifles. The research results can be used as a reference in weapon design, optical sight design … especially in the case of heavy rifles.
