I’ve shot 1/4” mild steel plates with standard m55 ball at 50 yards and seen the holes…
I suppose, maybe,… if those windows are built like bulletproof glass, layered up with vinyl in between then maybe?.. it would stop that round?
But the video isn’t about testing glass… it was about testing average doors.
Personally, I’ve seen enough of these kinds of videos that I know any stick built house is basically a fish barrel.
If you know where to shoot you probably won’t miss.
No interior or exterior wall will stop a bullet, unless it directly hits a 4x4 or the long dimension of a 2x4!…. And even then it may only deflect and continue on.
So unless you live in a house built out of solid brick, exterior,… and INTERIOR walls,… with concrete floors… do not assume your rounds won’t hit your neighbors!!!
