nice video! pretty much just what I was looking for, question though, would you say either of these rounds would be quiet enough to shoot in a residential backyard? I'm looking at getting a Savage MK II but don't really have easy access to a shooting range - I have enough room in my back yard to shoot and often shoot pellet guns in it but I'm not sure if super colibris would be quiet enough? Don't wanna annoy the neighbors...
