Judging by the holes in the water jugs, both rounds appeared to tumble. While the .22LR bullets did deform, it wasnt enough to make a significant difference. The more rounded shape of the .25ACP certainly punched a larger initial hole in the wood and I would assume that the larger bullet would also cuase more damage throughout the penetration under the (safe) assumption that both rounds were traveling at approx the same velocity during penetration of the water jugs.

But the point of the test was to measure penetration, not damage. However, it seems that the .25ACP outperformed the .22LR in every way.
