Self Defense Ammunition question

[Defaultmp3]

Someone here has probably done this (LE guys I'd guess). I've only shot auto glass once years back, and I didn't have bonded. Everything 5.56 sucked... even M855.

I can't remember where I saw heard that you hold a little low for straight on car windshield shots... but it wasn't some youtuber douchebag or anything. It was a legit source.

If shooting laminated glass, AP does best, followed by bonded, then monolithics. M855 does not perform noticeably better than M193.

Bullets deflect up when shooting out of a vehicle's front windshield; they deflect down when shooting into the front windshield. How much deflection depends on the angle of impact. Realistically, shooting out a vehicle sucks, due to the fact that the deflection can be massive, due to the fact that it happens at the very beginning of the bullet's flight, and thus impacts the trajectory significantly, hence why folks strongly recommend simply creating a big enough hole to shoot out of without the bullet impacting the windshield at all. On the flip side, shooting into a vehicle through the front isn't such a big deal, since the deflection occurs only at the very end of the trajectory, and thus has much less of an impact on the overall change in POA/POI.
