A huge difference! The hevi 7 is only 12g/cc on a good day. It's not much denser than lead at 11g/cc. Heavyweight 7 is 15g/cc. It's heavier, therefore hits harder. On the flip side, it's heavier, so you don't get as many pellets in the load as you would a hevi 7. Patterns are still good with the heavyweight and will have killling power to beyond 40 yards. The heavyweight shot is round and uniform. I like the heavier shot in the 20 ga.
I'm not a big fan of hevi 7s. They look good on paper, but I'm not sold on killing power. I have lost some with them in 20 ga and the loads were nitros. I'm sure they work just fine, but I'm paranoid about them now. Federal heavyweight 7s were by far the best commercial loads available and I hated to see them discontinued.
Yes is 18g/cc, some even 19. It's the hardest shot available. That's why you can drop to a small shot like a #9 and kill further than we should talk about. That is what makes it the most lethal loads you can get.
