[QUOTE="FearNoWind, post: 941107, member: 50867"] Up to a point I think I understand what you mean but if Sg is a factor of the ratio of an object's mass to its cross-sectional area we can't take caliber out of the equation. Lower the sectional density, increase penetration and delivery less energy to the target. Increase sectional density, decrease penetration and deliver more energy to the target. If I'm in a gun fight with a .22 I feel more vulnerable than I would be in the same gun fight with a .45. [/QUOTE]
