We wanted to know exactly what happens to a self-defense handgun bullet on impact, so following FBI protocols, we fired five rounds of Prvi Partizan 185 grain 45 acp SJHP from 10 feet, through four layers of cloth (to simulate clothing), into synthetic ballistic gelatin. The photos below show the bullets recovered from the gelatin after being fired from a Kahr CW45 pistol. There’s also a high speed video that shows the bullet impacting the gelatin block.

All the data we gathered pertaining to expansion and penetration of this load can be found in the chart below, and the diagrams at the bottom of the page show how it compares to other .45 ACP (Auto) self-defense loads from our tests.

In addition to the .45 ACP (Auto) Prvi Partizan 185 grain 45 acp  SJHP, we tested over 100 other self-defense loads, so check out guns Valley for the full story.
