I have overpenetration concerns in my house. I load Remington Duplex birdshot right now. They are an old version of what Remington is now selling as a HD load. I used to load Federal Home Defense #2 shot, but it never patterned well. I found out it has a "spreader wad" in it. It's been discontinued for a few years I guess, but I bought lots. For anything outside I use Federal low recoil OO with the Flite Control wad (now discontinued for civilians, email Federal please). More of the same and some Federal Truball low recoil slugs in the sidesaddle.
