If I block a fence row or the birds are flushing wild I carry my old Mdl 12 Super X thats chambered 3" for distance.If the birds are sticking or good snow,dogs working,idea conditons walking I will carry the Mdl 101 Pigeon Grd 20 in 3" with a load of 6's.If I'm limited of gun carry space I'll just throw in the 2 barrel set Mdl 21 12 gauge and make do.
