Madd Maxx .665 choke, 870 super mag, 3.5" Win. Extreme HV #5's-2 oz.

30yds, averaged 116 pellets head and neck.
40yds, averaged 86 pellets head and neck.
50yds averaged 45 pellets head and neck.

I never needed Heavy shot of any kind. Make sure you try different loads too as my gun shot the 2oz loads much better than the 2 1/4oz loads.
