I live the magpie goose season, but I do prefer farm shoots to public land.
On public land you can only shoot a limit, it was 7 last time I was up there but dropped sown to 3 the following year, but on farms you can shoot a, hundred in a morning.
I've gone through a case if 3" BB's in a morning shoot on Mellon farms, and dropped around 180 birds, that really fills, the freezer up.
But public land is fun because of the challenges, the birds are higher and more wary of anything out of place.
I found the best method at Harrison dam was to sit in the trees as they flew lower, once they hit the clearing they go much higher.
I will have to dig up some old photos.
The birds are very water dependent, I hunted shoal Bay a lot, the trick there I found was to figure out where they roost and shoot them there of an afternoon when they would break from the trees when spooked.
On farms 2 3/4" 2's work great, but on the public land 36gm 3" BB's are the go.
You can sit right against the tree line and gear them coming then drop them before the climb, I never had much success with decoys, intercepting the flight path from cover seems to work the best.
In shoal Bay the river shoots better then the 3 main swamps, but you can bag out on the main swamp.
