I don't own one but have shouldered this one a few times and really liked it.
I'm sure it feels great until the 3.5" Shell explodes in your shoulder with no Recoil help whatsoever!
There's just no way for me.
3.5 Shells just aren't needed for Waterfowl which is what I hunt the most. For Geese they do help but again aren't a necesity.
I shot a box of 3.5" Hevi Shot #2 on the last day of the season through a Benelli SBE II and paid for it for 3 days!
Didn't kill anymore ducks than normal.
Meh
Benellis are notorious for a "sharp" recoil, one of the attributes of the intertia recoil system, but it's not a problem with the 400 extreme
Heck, there's a Few options for 10 gauge O/U's if you want to be really manly!
I'm pretty busy right now, but I feel a sherburne visit coming on as soon as I finish painting my house! Do you ever pass through the Gonzales area? If so, I'd loan it to you and let you take it to shoot whatever you want, just so long as I get it back in one piece.
