Well, today was loads of fun. Unfortunately, my camera battery wasn't up to it, so I don't have any pictures, but I can provide a brief summary that does differ from some of the Box-O-Truth findings with regards to bullets penetrating automobiles.
The car was a 1997 Honda civic that was headed for the scrap yard with a blown engine, so we decided to have a little fun with it.
The very first round was a .50 BMG black-tip AP fired head on from 70 yards. It entered the front bumper about 8" right of center, passing through the AC condenser, fan motor, exhaust manifold/catalytic converter and hit the head of an AC compressor bracket bolt. The bolt was gouged about 3/4 of it's length, the bracket was shattered and the boss on the engine where bolt had threaded into was torn off, but the engine itself was still in-tact.
The next round entered 6" left of the first, passed through the radiator and entered the same hold where the number 3 rod had exited the engine. It must have hit the crankshaft, because it did not exit the block.
The third .50 AP round entered the grill, destroyed the hood latch assembly and lodged somewhere inside the cylinder head.
The fourth .50 round was standard ball fired at the passenger door from about a 70-75* angle. It ripped the door skin open in the shape and nearly the size of a football, entered the inside of the door, gouged the rear seat, penetrated the rear seat back and then exited low in the trunk, deflecting into the ground rather than leaving an exit hole in the rear bumper.
Now, we wanted to see the effectiveness of handgun rounds. We started from the front, shooting through the windshield from 10 yards. The 158 gr. JHP .357 rounds had no trouble piercing the glass and the seats, but did not exit the rear of the vehicle.
The .45 ACP 230 gr. FMJ rounds reliably penetrated the glass, with only 1 of 21 deflecting. The rounds that got through did penetrate the seat (one lodged in the steering wheel).
The 115 gr. FMJ 9x19mm loads had about 50% success getting through the glass and the rounds that did penetrate deflected badly.
I didn't have a 10mm with me today, but we can probably figure similar performance to the .357 rounds.
Handguns from the side. First up was the .357, and the windows were up. All three rounds fired entered the driver door and exited the passenger door.
The driver window was lowered and the .45 ACP fired through the door. The round shattered the glass and also exited the passenger side of the vehicle.
The 9mm rounds lodged in the passenger door.
Rounds fired later continued to prove that on a modern automobile, doors are not good cover. The only rounds that didn't get through were the very few that hit the safety crossbar or heavy parts of the window regulator/track assemblies. The inner and out sheetmetal and interior panels did little to slow handgun rounds.
Then we stepped back to 70 yards again, now with a G3 and an M1 garand, both firing 150 gr. FMJ. Both rifles were fired repeatedly into the left-front fender, and all the rounds made it through to the engine, destroying the motor mount, timing belt, cam sprocket, etc.
Now it was time to see what .204 Ruger with 32 gr. V-max's was capable of. The rounds were fired at the driver door and quarter panel. Not one of them fully penetrated the vehicle; a few left some dimpling on the opposite side of the vehicle.
.22 Long rifle rounds performed similarly to 9mm bullets, with none exiting the far side of the vehicle.
After the initial pokes, it was pretty much a free-for-all, turning the car to swiss cheese.
Though our results differed a bit from BOT, and our testing was less scientific, the conclusion is more or less the same; Cars are not good cover, unless the engine or transmission/transaxle is between you and the incoming rounds. The newer the car, the thinner the sheetmtel and lighter the components, meaning they afford that much less protection.
On that note, one or a few rounds cannot be counted on to stop a vehicle by crippling it mechanically; even that mighty .50 cal AP round that was fired first would not have stopped the engine-and this is a Honda, not a heavy duty pick-up or large SUV. There's just a lot of stuff at wierd angles for bullets to be stopped/deflected by in an engine bay.
I have another vehicle that will be perforated before heading to the crusher, so next time we'll be sure to get video and perhaps spend a little more time setting up the shots for more precise measurement.
BTW, shooting cars is SOOOOOO much fun
