Back in the 60's my brother had a Karman Gaea. I was 8 or so and like a horrible little kid, I shot a side window with my BB gun. 1 shot 1 kill. The window shattered. I shot my 200gr Super Police loads through a 2" M 10 and it went through a 1200 page Cabalas hard bound catalog and a gallon jug or 2 of water. I can't imagine it not going through a cars side window at point blank range.
