Borrowed a Suppressed Handi from a friend to shoot Beaver in a populated area. No one knows I am shooting beaver with a .308. Picnickers less than 50 yards behind me and no one hears a thing. Due to bears in the area people do not let their kids roam from the picnic site. The few people that have seen me unloading and setting up think I am carrying an air gun, and they don't have a problem with that.
I set up a portable blind to hide me from their view. No noise, No fear. When I shoot the only sound heard is a slight whisper, just like in the movies. The sound is not load enough for anyone but me to hear. The same sound you hear from a blow gun, just not as loud. The bullet striking makes more noise than the shot.
It's great, I shoot, a beaver flops, I select another target and shoot again. I wait for the perfect shot where the Beaver is out of the water far enough he won't flop back into the water. While a head shot kills them instantly, the body still flops around for a few seconds. Then just before dark I walk down dragging a plastic sled on the grass. I pick up the beaver and haul them back to the truck. I can get three of four an evening, and never upset the beavers or people.
Also due to bears in the area I am not going to be doing this after dark. Picking up a bloody beaver after dark in Grizzly country is not a bright idea to me. Plus the subsonic loads I am shooting would not be good for defense. All they would do to a bear would be to get his attention, and not in a good way.
