Larry, they have a place for me for training young shooters. I have been teaching young shooters for many years and the 28 ga in a semiauto like my 1100 Sporting is the way to go.
Shells are prohibitive in cost so I buy new hulls from Ballistic and load them on a MEC 600 adapted for 28ga.
Apart for training, I have used 28 ga for grouse and pheasants for years and the cartridge performs well above its weight, as many will attest.
Load you own is the secret
