I won a .673 angle port for my SBEII - I talked to Reloader about it and he confirmed my beliefs that it was probably gonna be too open for a Benelli. I ran some 3.5 MB's and 2.25 #6 hevi's through it and don't remember the exact numbers but both were right around 190-205 (off a dirty bore) and the patterns were as even as you could ask for(more even than the .660 JH). I know thats not up to you guys standards, I was really surprised, it was exactly what I was looking for. guess you never can tell till you run a few through it
