Thanks for all who responded. I contacted Benelli and was told that my set up was perfectly fine. Was informed that what ever is comfortable and works best is how it should be set up. I did try it straight out of the box and was hitting 2 of five traps, consistently missing high. Yesterday I went out after confirming that I would cause no damage to the gun and leaving my set up mentioned as above and was dead on, hitting about 80% to 90% at 30 yards (Impressive for me). C Drop shim really gave me better sight of the figure 8 bead pattern, without seeing nearly as much barrel rib, which I think was my main problem shooting high. As far as Cast well I am still stumped, I dont know if what I have set up is correct but it works for me!! As far as I am concerned, thats what matters. I just didnt want to damage my new favorite pump gun! I am dove hunting Friday and will be putting her through the ultimate test. Thanks again for all the help! Happy Shooting!
