A lot of theory and a lot of speculations are just that. The following picture is of 2 bullets that I removed out of recently deceased antelopes. Each animal had been dead less than 1 minute. On each antelope I fired 2 rounds of ammunition at a severe going away angle, aiming for the last rib toward the off shoulder. I used a Ruger LCP, I used a Cor-Bon DPX's on one antelope and Remington Golden Sabre's on the other. On each antelope only 1 bullet was recovered. First the DPX that was recovered had the bullet entering between the last 2 ribs not hitting any bone, and had made it to the off shoulder, again not encountering any bone on either the shoulder or ribs, approximately 18" of penetrition mainly lung tissue and light muscle. The other bullet failed to exit as well but was unrecovered. The next antelope was a very small antelope, not shot by me, again fired from the last rib angleing to the off shoulder. Again no bones were hit on the enterance or where it came to rest in the muscle of the off shoulder and the bullet had only 9" of penetration. The second Golden Sabre was at the same angle, had penetrated 11" and exited and was unrecovered, again hitting no bone. Later on that year I shot an average sized mule deer buck in his heavy winter coat, both shots were broad side lung shots. Both using the Cor-Bon DPX bullets, both bullets completely penetrated the animal and exited and were unrecovered. No rib bones were hit with either bullet. For some reason I just cannot seem to hit a rib bone with a .380 to determine its capacity and penetration. This as always is not a mine's good and yours isn't, these are just actual results.
