Jacketed round-nose pistol bullets will penetrate 24-27 inches in ballistic gelatin, and hollow-point bullets will penetrate 12-14 inches despite opening up into a true blunt impacter. | |

Jun 21, 2017 at 17:27 | comment | added | Draco18s no longer trusts SE | I'm interested in knowing why the density relates to penetration depth. I mean, I realize that physics would say that it is, I'm just curious about the math involved to go from X-g/cm3 to X*length. | |

Crossbows work quite well with wooden quarrels. Evolving technology might take a path that leads to some sort of explosive-propelled derivative of that. | |
