Pretty illegal to actually shoot from a vehicle here unless you're licensed handicapped, so no idea about shooting A and B pillars. But.....ahahahhaha, there was a fella, back when I was growing up, that went out target shooting and decided his hood made a good rest. Shot through the hood and opposite fender of his pick-up. He learned his lesson though. The next weekend, he decided standing in the bed was better. Shot clean through his roof and front windshield. Ughhh, it takes all kinds.
