Shaped charges with higher jet tip velocities result in more residual penetration behind special targets, as demonstrated by bulging and ERA sandwiches, compared to charges with lower jet tip velocities. Shaped charges with larger base diameters give more residual penetration behind special targets compared to shaped charges with smaller base diameters. They still have the same penetration potential in semi-infinte rolled homogeneous armors (RHA). Precision shaped charges with the same base diameter as normal shaped charges give more residual penetration behind special targets, even the differences in depth are mostly remarkably reduced.
