I know that I've gotten better performance from my Hornady 8 pellet loads in both my 870's and my Ithaca 37 then I got from 9 pellet Federal.
I patterend all my shotguns out to 25 yards (5, 10, 15, and 25) with different loads (Winchester Ranger, Federal Tactical, and Hornady TAP) before I settled on the Hornady. Though I don't use them for HD, my Stevens 620 Riot and Winchester 97 Riot also did better with the 8 pellet loads.
I've heard very good things about the 8 pellet Federal that came out earlier this year/late last year, but haven't tried it.
