Now fire it within the car. :)
40 years ago, I owned a bar and was concerned about carrying large amounts of cash {we did a tremendous cash business in the 70s} and I had a carry permit.
I wanted to find out how my 357 Magnum would perform inside of a vehicle. I went to a friend that owned a junk yard and sat inside of several vehicles and fired out at different targets {I did have ear plugs, ear mufflers and eye protection along with a leather jacket and gloves}.
I hit center mass through the windshield and both front side windows but missed shooting through the rear side windows.
I had ear ringing for over a week, but I knew that if I had to, I could shoot through the car windows and mostly hit my target.
