Thanks, this is good info. I confirmed without a shadow of a doubt I need a little more "umph" in my arsenal this weekend. My poor old light A5 didn't quite have the reach to communicate with some geese that were above my head. Tough shot for me any way, but I wasn't going back out and it was almost dark.
This is the first I've heard of the bennelli click, but now that you mention it, my old 1201FP did the same thing as what you described. Might start checking out gas guns because of this. I'd love a benelli, but man are they $$$
I'd read that any bumps or jarring of the shotgun can lead to this so I got in the habit of retracting my bolt and letting it slam home periodically which did seem to reduce but not eliminate the problem completely. It was always the first shot only, the other 2 always fired perfectly, and it wasn't a huge issue for waterfowl hunting as long as I remembered to retract and release the bolt before taking a shot.
