Yep, and some things aren't obvious.... like round nose (hemispherical) pellet penetrating just as well as pointed ones.... Softer pellets penetrate less ONCE they start to expand, but unless they have a flat nose or hollowpoint, that doesn't really happen at airgun velocities.... and even then HPs differ widely in the velocity it takes to make them expand.... ONCE they expand, however, their penetration decreases rapidly, replaced by a wider wound channel....Bob
