I have to be brutally honest and say that people do change their chokes for all sorts of reasons. If you think changing the chokes will help you break more targets then there has to be a reason for you thinking that? I changed because the lighter choke made my barrels a bit more mobile and the ones I chose were said to give a slightly more open pattern. My experience with them was yes they did make the gun barrels more a little faster to the target, I never patterned them so I cannot with honesty say they are a more open pattern but would say they probably are. The main question has to be though did I break more targets due to the pattern they threw... I don't think so to be honest the main difference is the weight . I am really saying that if you take two chokes that are of equivalent nominal choke I don't think you will break more targets because of the pattern, If you are one the target you will smash clays with the original chokes just as well. In summary don't go changing chokes in the hope that they are in some way magic and you will improve your score... on the other hand the placebo effect is a powerful driver
Do you know anybody who has a Beretta and uses them you could try theirs out in your gun to see how they feel.
