For those of us that routinely practice predator control for waterfowl conservation, you may want to try a box of these .22 shells.
The advertised velocity is 970 fps with a 45-grain hard nose tip. From my recent experiences, they are quiet and very accurate. The neighbors didn't hear a thing this morning when a trophy sized Ditch Tiger took a dirt nap. Normally with regular .22 ammo, I'm getting asked "What did you shoot today?" So far, no one hasn't a clue that I even fired my gun.
At $10.00 a box, they are not the cheapest found to be found, but if quiet is what you are looking for, look no further.
