First time I have ever used this gun and the first time I have ever used a gauge this big for pen raised birds. It certainly "reaches out to them". Using Gamebores Traditional 2 1/2" #7 28 grs powder and 1 oz. of shot. I don't think these are low pressure. The setter is Max, 18 months old, his first year at pheasants and chuckers (pen raised) doing well so far, needs more birds like any bird dog.
