Ok guys, no insults or personal attack will be allowed in the comments. keep it clean. this video is a learning example for following the rules of handling a gun, not a witch hunt.  #1 THE GUN IS ALWAYS LOADED. dont play with guns. don't point guns at stuff you don't want to shoot.

The phone can not record to the SD card or internally fast enough either. I filmed the second shot from the phone, and the video is corrupted. I used a free app to preview the file, and it does not show the last few frames before i shoot the gun. here is the file. https://drive.google.com/file/d/1nzQonW9JhQny5HWE8UpWnDfmWjcFZcdY/view?usp=sharing  use mp4 fixer on android to view the file if you want to see for your self.
