The battlefield experience against the Moros resulted in the famous Thompson-LeGarde tests by the US Military in 1904. In these tests a variety of military cartridges of the day were tested for their penetration, ‘stopping ability’ and energy transfer, using both live and dead cattle at the target medium. While somewhat subjective by modern standards, the tests resulted in an official recommendation “…that a bullet, which will have the shock effect and stopping effect at short ranges necessary for a military pistol or revolver, should have a caliber not less than .45."
