Look, if it was a good hit on both lungs, you wouldn’t have tracked the hog as far as you did without recovering it. From that angle, with that mid-body hit, you, at best, clipped his right lung, high. High lung shots generally don’t bleed as well and take longer to incapacitate the animal. I’ve done that on a deer, with a “good bullet” that exited. And then tracked the deer 500 yards on the ground (only 350 as the crow flies) before recovering him. One lung was wrecked, but the bleeding was mostly internal and it took a while for the tension pneumothorax (sucking chest wound) to kill him.
The ideal shot placement for your angle was slightly lower and slightly more forward.
