I had a car door to dispose of so we decided to try out a few different rounds in a real world test to see how they performed.
The testing site:
First, a 22LR with a lead projectile out of a P22. It had no trouble at all punching through the outer layer of the door, but failed to break through any successive layers inside the door.
A different 22LR ammo yielded similar results.
The KelTec P3AT passed through a part of the door where it didn't hit subsequent layers, so that part of the test is inconclusive.
The 38 special wadcutters out of the snubby didn't make it through the inner layer. of the door.
