My 870 with a 28" barrel likes the RSF better than the SSX with H13 #7's. I was right around 100 hits with the SSX, but the RSF put around the 130's consistently.
Here's one I saved from last year, 133 hits. I cut this out after finding the densest part of the pattern. I didn't shoot at a 10" circle, but the POI was pretty much dead on for this shot.
