Won an O/U a few weeks ago, Beretta 686. The gun case has 3 strips of foam padding glued to the inside of the case, and there are 6 pieces of loose foam padding that were in the case when I opened it. Is it customary to pack the loose foam pieces in strategic areas when putting the gun back, should I semi-permanently glue them in the strategic areas, or should I discard them? This is the nicest of all my firearms. Thanks.
