My club had a 410 shoot last October. I was behind getting this going. When I was getting things set up with the club owner we had agreed 3" shells would be allowed. Then some guys from the local Skeet club complained that would be like shooting a 28 gauge.
So at the last moment they changed the rules to 2 1/2" only.
After I had bought a flat of 3" shells.
