What is it about?
Shooting accuracy of air gun projectiles is very important in sport tournaments, and has always been questioned by enthusiasts. For this purpose, the performance of four samples of air gun projectiles (pellets) with various shapes and calibers of 4.5, 5.5 and 6.35 mm, were studied in this paper. The projectiles were four basic shapes: flat nose, sharp nose, round nose, and spherical. Computed results describe the trajectory, velocity variations and altitude loss of the projectiles with time and location. Comparisons indicate that the round nose projectile had the best performance in long distances compared to the other samples. The flat nose projectile exhibited great performance in short distances, but behaved weakly in long distances. Additionally, the effect of nose shape on the performance of the sharp and round nose projectiles was studied and the optimum nose shapes were identified.

Perspectives
Writing this article was a great pleasure as it has co-authors with whom I have had long standing collaborations. This article also leads to some of results which describe the trajectory, velocity variations and altitude loss of the air gun projectiles projectiles with time and location which always been questioned by enthusiasts. .
