Analysis was conducted by looking up gelatin data on various cartridges. A total of 422 shooting results were analyzed and plotted. Analysis was primarily based on Energy and Wounding Potential. Energy in foot-pounds was calculated by the following formula: 1/2 * (M/7000/32.174) * V^2 Where M is bullet mass in grains, and V is bullet velocity in feet per second The Wounding Potential in cubic inches of a given bullet was calculated by another formula: PI * (D/2)^2 * P Where D is expanded diameter and P is penetration depth Energy was plotted as the abscissa, and Wounding Potential as the ordinate (X and Y axes, in layman's terms), producing this graph: While it appears at first glance that there is some correlation between Energy and Wounding Potential, further analysis reveals that this is not the case. When all "mousegun" calibers (.22 LR, .25 ACP, .32 ACP, and .32 NAA) are graphed together, there is still some correlation: However, if all 9mm calibers (.38 SPL, .357 Magnum, 9x17mm Short, 9x18mm Makarov, and 9x19mm Parabellum) are plotted, the result is: If all 10mm calibers (.40 S&W and 10mm Auto) are plotted together: And if all 11mm to 12mm calibers (.44 SPL, .44 Magnum, .45 ACP, .45 Colt, .45 GAP, .45 Schofield, and .45 Super) are plotted: Sources of test data: http://www.firearmstactical.com/wound.htm http://www.goldenloki.com/ammo/gel/tests.htm http://www.stevespages.com/page8f.htm (penetration depths divided by 1.5, as this is the approximate ratio between water penetration and gelatin penetration) http://www.handgunsmag.com/ammunition/ 2 more graphs in next post (limited to 5 attachments).
