Could a gun cause this hole in window glass

[John "spysir" Blount]

Pictures look like impact from outside and lobbing in from above - assuming the glass was perfect & level/square- . .30 something from 1,600 yards?

But anything solid enough to penetrate that would be in the house someplace. Wouldnt think it was any bird we have in the U.S. , or elsewhere.

Glad ya'll are okay.

Had a teenager in the neighborhood that was launching rocks at passing vehicles. The little $hit got dozens of cars and trucks. He was throwing strawberry sized rocks at vehicles doing 40-50 mph. He got me three times in as many months. I never had the window penetrated on full sized pick up trucks, Something smaller at a high speed, rock lawnmover, or something propelled from a tire. If a bullet did it something would be inside.

You know, cant rule out space debris. Just saying!

Quite possibly caused by an over stressed spring on a cloths pin carelessly attached to that suspicious line on your side of the fence, that is now carrying what appears to be bath towels. Those springs harbor great amounts of mechanical energy that once released could take out an eye or window. A good example of negligent laundry care if you ask me. Your 11 photos were very helpful in my Crime Scene Investigation.

It was a low velocity "projectile", like a rock. If the scalloping was on the inside, then it hit from the outside. A "round" or bullet or the like would leave a rounded hole for the most part, as there is equal stress coming from all sides. A rock would leave a hole like that and you won't necessarily find the rock inside the house. I have seen dozens of holes like that and dozens of holes from bullets. I'd guess (without an actual test) that it also hit from an angle - in other words, not coming at the window from a 90 degree angle, but more like 15 to 65 degrees. If someone threw a rock and it didn't hit hard enough to go through, it would glance ("bounce") off and then it could even be 10' to 20' further down the wall/window from the point of impact.

So I wont make everyone guess but here is what a 22cal 25gr JSB redesigned does to a window at 165 yards after passing thru 40 yards of standing corn. Hole was almost big enough to put a soda can into.

Glass is funny. It can stand enormous impacts and never crack. Then again the slightest touch can cause it to shatter. I have to agree that this was most likely a rock.it would not have to be thrown very hard to do that level of damage. The lack of a found projectile inside rules out a gun. My guess would be a kid messing around and probably recovered the offending object.

Thank you very much for your opinions guys. At least no one's shooting at me house. I hope to God that prick of a vandal gets some life lesson. The coppers know about this incident and hopefully they'd do something about it. 

Cheers

Just a thought, but could the car have flung a rock? Something like perfectly run over by the edge of the tire and launched under pressure.

I have saw this first hand some years ago flagging traffic.I had just released my traffic to get by the work site when the 2nd car in line did just what you described,it's side wall pinched a piece of gravel just right it flew out from the side and literally knocked a lense outta my raybans.The lense actually cut my skin just at the cheek bone.I was absolutely astonished such a thing was even possible

Gotta tell a story about my wife's Aunt Mardell inside window damage.

As was told by my wife's uncle Ralph aunt Mardell was a 350 pound woman who was married to a 110 pound guy and Mardell liked to "squish in the flab" using a corset, however occasionally the corset would give way to all the "pressure" and Mardel would "force" her husband to return the "blown up garment" for a refund due to "faulty materials".

Well, as Ralph told the story, Mardel and her husband were invited for dinner and while sitting at the dinner table Mardell's corset "let go". The force of the "explosion" popped off the really large buttons on the front of her dress............one button gave Ralph a black eye and another button broke the dining room window from the inside.

Not really airgun related but I "hadda" share the story that seems to be a "made up tale", however several of my wife's relatives said it was a true story. LOL...there is another tale of how Mardel broke a rear spring in Ralphs car when she plopped down in the rear seat.

My opinion on this one is simply "who knows" It could have been just about anything. As far as the button coming off the dress and causing a black eye and breaking the dining room window? To say I'm skeptical is an understatement. You'd have to have that corset cinched up with some elastics I've never seen on any garment. Probably kill the lady restricting her circulation and breathing before it would send a button into orbit.

I bet some Ahole monk walked by and tossed a McDonald straw at the window. They do that kind of stuff.

Without writing a book, the conchodial fracture that allows glass to be knapped into arrowheads leave behind other clues. The feathering seen from the internal cracks left behind show that whatever it was was angled down when it hit, driving several long wedges off the lower side and causing internal cracks because it struck at the correct angle to make those internal cracks.

A rock thrown by a mower or maybe a person.

The upper edge is almost square because the object was arcing down. That put it at the correct angle to drive the crack almost straight through on the top, and at the correct angle to drive the cracks deep into the glass on the other side.

I hope that makes sense, but the short answer is that glass breaks at a predictable angle when struck, and that shows the path the object took.
