"IE front yard" however I do shoot in the back yard out of the view of the public. I always use a pellet trap. I own several air guns. Lets just say more than 20, BB guns and spring powered air rifles I shoot in the back yard. High powered (PCP) air rifles, These are the ones used for hunting large game, up to 50 caliber, I take to the range. Did you know that air rifles have a noise rating. See link # 2 below. Then click on the rifle and open the specifications to see the noise rating
@ 3,500
