The 686 is the entry level gun from Beretta. The next level up ( around $2500 ) is the 687 and 682. The 687 and 682 are virtually identical, with the differency that the 687 is aimed at the hunter and the 682 at the clay shooter.
I have the 682 Gold E for clay shooting and I am very happy with it.
My second question is about 3 1/2" chambered over/under . Will 3 1/2" o/u (or any other) shot the same 2 3/4" sheels as 2 3/4" chambered identical one ? I mean "freebore" effect etc. What do you think about this ?
I asked about this "possible" freebore effect because I don't understand why most of shotguns is not made with 3 1/2" chambers. So if problem with pressure is not the key (same actions for 2 3/4" chambered and 3 1/2"), what is the key ?
In general, most shotguns are not chambered in 3 1/2 due to the extra length requirement it puts on the action. Although this does not impact an o/u, it does all moving action guns.
It also plays a role in barrel length and in back boring of the barrel and the forcing cone ahead of the choke constriction.
Also, there are a few differences in the 687 and the 686. The 687 has nicer wood and offers the opportunity to have side plates. Also, I believe the 687 action comes in a true 28 gauge receiver, versus a 20 gauge receiver for a 686. However, I am not certain of this...

The "pros" have long felt that the best patterns from a 2-3/4" shell are via a 2-3/4" chamber.
It is rare to see a dedicated trap or skeet gun with anything but.
Perhaps you have read up on forcing cone length / angle? What good could an extra 3/4" of "nothing" do to your shot column?
