Claudio just gave you the best advice you are going to receive on this forum. Shaving a few ounces off of a 7 pound weapon does not a woodcock gun make. If you are content to carry a 12 gauge that weighs over 6.4 lbs. through the alders, you are not concerned with weight but balance. I believe Trevallion wrote a series of articles for DJ on adjusting the balance point with weight. Throwing money at a problem does not always get the best result.
