Try on a Benelli for size. They run flawlessly.
Yes, with the ammo that runs the gun, which is typically a warmer and heavier load that will run a gas gun. However, if you add some weight to achieve more recoil reduction or to better balance things out, then you have the real possibility of making the Benelli unreliable.
Don't get me wrong, they are great guns for what they were primarily designed for - nasty hunting conditions. If I was a waterfowler, they would be near, if not at the top, of my short list for a go-to gun.
That said, the topic was about a clay target gun. In this scenario, the "brother from a different mother", Beretta, is a better choice (and typically less expensive). I have 2 A400s, the blue smurf gun and the green 3.5" monster; and BOTH have handled my 3/4 reloads running 1275 with zero malfunctions of any kind now for several years. Neither the A5 nor the Benelli can do that. I have nothing to turn around or change, I can load a mixed variety from those 3/4 to 3.5" retina-detaching shoulder busters and they will all function flawlessly.
(Whether I would after 3.5" is debatable )
The few folks I know who use Benellis for clay targets need to shoot either hot 1oz loads or medium 1-1/8 loads (like the walmart stuff) to make their gun run without hiccups.
