looks like you might just have to see how many good friends you have!

i got a recoil reducer for my nova, consists of a bracket that fits in the hollow stock and holds a cylinder full of mercury. havent tried it yet, if you have a wood stock, you can forgo the bracket and drill a hole in your stock and place the cylinder inside back it up with a peice of hose and put your butt plate back on. the cylinder itself cost me 40 bones, but i got one of those bum shoulders too and the gunsmith said it will noticeably reduce recoil. the cylinder has to fit tight and dont go drillin up your gun unless your good at that sort of thing. it wont work if its crooked it your stock. good luck.

Try using a 2 3/4" or 3" shell with a target load. It will get you sighted in first. Once you are close than go to your turkey load and dial it in. Easier on the sholder and the wallet

I' m assuming you have a benelli sbe. If you do, the recoil reducer that cpac was talking about will fit your gun without any modification if it is a 2001 or newer model.
