I would like to throw out a challange to any who may have the time & inclination to run an extensive pattern teating between the 3" .410, 11/16oz load; the standard 28ga 3/4oz load & standard 20ga 7/8oz load. Testing should be done with guns having as near as possible same choking. Patterns should be evaluated on something such as the 16-field target & be evaluated for pattern percentage, central core thickening & uniformity between fields in both inner & outer segments. I no longer have the inclination, nor all the guns necessary, for such an undertaking. I think many, including .410 aficionados, would be surprised at the smallness of difference. What difference there was though I would bank on being toward the 20 having the least core thickening & the greatest uniformity, with the .410 having the opposites & the 28 between, but closer to the 20. I would not be disapointed to be proven wrong, but I sincerely doubt it.
