Just curious why you wouldn't consider using the new Heavyweight in #7?

While at the NWTF convention this past w/end I spoke with the Hevi-Shot folks as well asreps from Federal, Remington, and Winchester. The Heavyweight #7 pellet, according to the person at the Federal booth, carries about the same downrange energy as a lead 5. But here's the kicker - the 3.5 inchload ofHeavyweight#7s hasover 500pellets. If retained energy is similar to a #5 or even #6 I would think this would be an awesome round.
