I have the safety off while sitting. The camera, an old Go Pro 2, does pick up any noise I make and magnifies it in the video. I’m really just saying, above, how fast the hogs react after the shot. Lots of people, on you tube, ask why not shoot more than once? Did they not watch the video?Question... are you flicking the safety just prior to the shot? If so, they might be reacting to that metallic "snick".
