These pellets are manufactured soft for easier expansion, providing incredible hydrostatic shock on impact which can be heard by the massive clap sound produced on impact. Their penetration is not much as they will deform rather quickly, even w/ a 40+ fpe rifle, causing a lot of inertia due to its Buller
