I use the Super Colibri .22's (advertised 500 fps) in a cheap yugo bolt action trainer on Grackles in my front and back yard. Neighbors have seen me and don't give a crap as long as I'm dispatching the nuisance. I have a cop that lives 2 houses down from me and I don't even try to hide from him. But I'm in conservative West Texas.
Best day was when I shot 3 grackles with 3 shots. My Grandmom taught me how to keep them away for awhile. Kill a grackle (she did this with crows) and hang it in a tree with a cord or rope. It works....try it.
