I have never had any issues with my Super V having cycling issues. I've shot 3.5" Black Clouds and Winchesters, 3" Winchesters, and 11/8 oz Remington 6 shot(dove loads). I know that when I spoke with Benelli before I purchased it we talked about the lighter loads and make sure that the drams of poweder were between 3 and 3 1/4.
No sir. If the dealer won't help you I would call Benelli. I bought mine last year and it's a fine shotgun to shoot. FYI and I'm sure toy know this, but cycle a box of 3" shells through it first before shooting the lighter loads. Enjoy.
