I went ahead and tried it. I went from the factory 60DX to the 65SX on the shims as well as added a 1/2" spacer on the LOP getting it to 14". When I close my eyes and bring the shotgun up to my eyes and open them. I don't see the top of the rib anymore, just the back of it and the front bead. I think that should get me a 50/50 pattern, I hope anyway.

I didn't really notice any side rib originally so it is hard for me to judge if the "windage" is better or not. I was going to try to take it and pattern it tomorrow if I have time to see if it is "fixed". I typically have always shot better with
"US" shotguns that I have owned, (Browning/Mossberg) than European (Benelli). From my research the typical "US" shotguns normally have neutral cast on the stocks while all the Euro guns have RH cast from the factory.

The question is did the SX move it to the left of center or just center.

I guess I will find out tomorrow.

If I can't get it to work, I see a Maxus II in my future. smile
