Don’t want anything to do with powder as I said can’t have it shipped and every purchase requires a background check in NY . I don’t worry about noise here I shoot the 30-06 and the .40 in my backyard the sound of gunshots are very common here. My brother in law was very nervous when he came up and heard gunshots most likely a neighbor sighting in his rifle for deer seasonHave you considered CCI St. Velocity .22lr? It's actually quieter than air rifles, sub sonic velocity.
