I have a few hundred geese on my property as I write. I want to scare them. They are here every day. I am looking for a type of shotgun shell that I used to get from a Washington State Game Warden that fired from a 12g shotgun with hardly any noise, would go a hundred feet or so and then would explode with a loud bang. Any ideas what these type of shells are called and where I might find them? Thanks for the help.
