Subsonic ammo is highly prone to ricochets. So, be aware of that. I shoot squirrels in the woods with CCI Standard Velocity and a suppressor and more often than not, I hear the bullet ricochet off somewhere. I love using it, but don't like to hear the bullets zinging off somewhere. If I lived in an area that was legal for firearms and had homes nearby, and all you wanted to do was get rid of pest squirrels, I'd shoot a shotgun and know that there would be no danger of a ricochet. The neighbors would just have to get over it.
