Unleaded for me. I still have some Hevi-Shot "Old White" 3", 1.75oz, #6. I'm running those through a Rhino .660" in my Benelli Vinci. That was a great load. IME, the current 2oz #6 load won't match it. I'm also running some of the Hevi-13 2oz, #7 through a Jeb's .670". The more open choke is throwing an even, wide pattern with nice 10" core density to 50yds. Then, I also tinker a bit with tungsten. I've been loading 2oz #8x9. However, I may move to straight #9s and a more open choke like a .675" and .680".
