Shot a 12 Remington 870 special purpose 3" for years., killed many birds with shooting #4/#5 Mag Turkey loads. About 15 years ago I went to the 20 ga. Had outstanding results with the smaller gauge. Shot TSS with it for several years #8 and had great results, went to a Charles Dailey single shot 410 bore last year using # 9 TSS , 1shot 1 dead turkey. No I did not shoot him at 80 yards, was about 35 yards but stone cold dead. So you gays go ahead and shoot you 3.5 inch 10 gauge if you want, all you are punishing is yourself (IMO)
