PDW trunk gun quest

If these Wolf 120s MPT can do this to 7/16" steel, I would think a windshield wouldn't stand a chance.

Yes, and no. If the windshield is perpendicular to the bullet's path, as it was with the steel plate you shot, the MPT should have no difficulty penetrating.

The problems arise because the firing angle is usually at much less than 90 degrees. Combine that with the compound curvature on both windshield and bullet ogive, and there's a chance the projectile will be deflected from its original path when it hits the glass. If the angle is shallow enough, some bullets reportedly have even glanced off without penetrating.

One aspect of designing "barrier blind" rounds is to create a projectile that will experience minimal deviation from its path after punching through the windshield. Question is, how does the MPT (or any other Grendel load) do in this regard? Anyone have a spare windshield lying around?
