Im fortunate to have good neigbors. They probably shoot in there yard more then i do. I dont really like doing it much as i really dont like the idea of people knowing i have what I have in the house and barn. Only one time did a state trooper come to my yard on a complaint. I was bump firing an AR one day and someone called and said a machine gun was going off. I explained to the tropper what i was doing and before he left i had to teach him how to do it! He left with a smile on his face. As to your question ive shot round balls out of a 45 colt with 1 grain of bullseye. I really dont think it was much quieter then a 22 though. It lacked the crack of a bullet going supersonic but still makes enough noise that a neighbor would hear it. Buy a bunch of fireworks and light some off every week to get the neigbors used to the noise and they probably wouldnt know the differnce.
