Any rifle round will go through it. Some pistol rounds will.
True story. I had a '73 Lincoln Continental Mk VI, lovely old blue boat, you could land an aircraft on the hood of the thing.
I drove the hell out of it for years until I turned a piston sideways in the 460 dumptruck motor under the hood. I made it home with the bottom of the oil pan completely gone, and parked it out in the back acre. It never moved again.
It became the target/backstop for light arms practice.
At point blank, the heavy .45 pistol rounds would not penetrate the door. They rocked the old boat, but they didn't enter the passenger compartment.
A .22 rifle round would easily pass through the door and usually got stuck in the far door from a range of 50 meters.

There is a metal piece on both sides of the door.
A zombie would likely have a hand gun rather than a rifle. To be safe, then, I shouldn’t stand in front of the door. There is a door to the laundry room immediately inside that door, so I could stand in that doorway and be out of the line of fire if someone shot at the door.
This has been bugging me for some time - was it safe to stand in front of that door if someone knows I’m there and shoots at the door. The answer is, from what you say, I’d better not stand there.
