I'd say closer to 5". I'll have to shoot paper next time to see. My video skills are getting better but my software sucks. I need a better SD card for the down range camera so it will take better video. The camera at the bench records in 1080p. My software reduces quality and then uploading to YouTube makes it worst. In the video you can see the bullet in flight barely. On the raw 1080p video I have no problem seeing it almost all the way to the target. I'll try and upload that tonight and see how it looks.
