Good points, Miller. I have not seen an increased core density in the .410 over other gauges in my patterning. However, I believe in tight choking for a .410, which "tightens up" all parts of the pattern, with increased density in all areas of it. That is probably a big reason I have had the success with it on birds that I have. Downside to that, of course, is a smaller overall pattern diameter, giving less room for error in lead, and in being off-line.
