Abstract
The Directorate of Land Requirements (DLR) has requested the Defence Research Establishment Valcartier to carry out an investigation into the performance of various heavy calibre sniper rifle systems. The objective of this part of the project is to establish with a common simulation methodology the performance aspects related to flight of a wide range of projectiles and to assess their relative importance. A total of fourteen projectiles distributed through four calibres (7.62 mm NATO, .300 Winchester Magnum, .338 Lapua Magnum and 0.50 cal.) were investigated. The geometry and mass properties of the various projectiles were measured. Then, these results were used with the PRODAS software to obtain predictions of drop, velocity, kinetic energy, stability, and sensitivity to launch conditions and wind. These predictions indicated that the different design strategies used for the projectiles (combinations of inertial and aerodynamic properties) give different performance characteristics and that no single design gives the optimum characteristics for a sniper projectile at long range.
