When discussions turn to gun weight with the 28g and .410, I think it gets down to very personal preference and abilities. Why should someone that cannot shoot a gun well, under say 6 1/4 lbs, but is very much a great shot, be looking for the "advantage" of shooting a 5 3/4 lb 28g? IMO, gauge and "optimum" gun weight (96X shot charge, etc) can be disassociated when going down in gauge to accommodate minimum gun weight/balance for the shooters abilities. The "advantage" of using a smaller gauge comes in the form of the particular hunter's satisfaction with what he is shooting.
