Two 1/4 sheets? Most doors are 1/8 when heavy built. No matter. A 308 can make it through both. If only a 1/8 sheet, then a 5.56 steel penetrator can make it through, barely. A 44 magnum or better would be required to make it through both sheets at 1/8, and that 44 bullet had better be a FMJ/TMJ and 240gr or lighter for the best velocity. A pudgy bear round like the 270gr Speer DeepCurl Soft Point probably won’t make it through both sheets very well. I have rang 1/2 metal targets with that 270gr bullet and it barely made a dent.
“Two 1/4 sheets? Most doors are 1/8 when heavy built.”
That was what I measured on the closing side of the door. I just looked at the other side of the door where it attaches to the hinges and that looks like 1/8 inch. That must be what it is.
So, there is some protection there but since I wouldn’t know what kind of bullet was going to be shot at the door, I’d better not stand in front of the door.
I was skeptical whether or not the door would be strong enough to deter bullets and from you and Johnny, it isn’t.
I think most people think their front door is protection from bad guys and that is false. One must have a “protection” device in his/her hand to have actual protection in a worse case situation.
Depends on the type of steel, the caliber, type of ammunition and angle. With the right ammo the 5.56 will easily go through a 1/4 in steel plate.
Steel targets are usually hardened steel and since they move they don’t absorb the energy, they deflect it.
The point is that unless you live in a home made of solid concrete or have 1/2 inch of hardened steel most bullets fired at your home will find their way inside. In a TSHTF scenerio the normal home does not provide adequate protection.
