That's why I use rounds that provide a level of penetration john holmes would approve of, that said, an 11 shot 870 is in the back loaded to the gills with 9 copper plated 20 pellets each of #1 Buck, with two Brenekke KO slugs bringing up the rear.
Jerry, I've seen a lot of good ballistics testing that endorses plated or hardened #1 buck. I don't have much street data for that load, however, nor does anyone else I know who keeps track of such things.
However: there is a LOT of good data showing 00 buck is highly effective, and since the "laboratory" ballistics of #1 and 00 are very close at home-defense distances, I think you're on a good track. I still use 00 buck as my primary load in my 11-87. It's not because 00 is a tad more effective once you get past home defense distances, but because I haven't been able to procure a decent supply of plate #1 buckshot I have to stick with the 00 loads I have already patterned and trust.
