Winchester Shotgun Shells

I use nothing but Winchester Australia’s 12 Bore 2 3/4 inch AAA cartridges in my 12 Bore William Wellington Greener side by side wildfowl gun for hunting greylag geese and for hunting Kakar Deer , during beats . They have never given me even the slightest reason to complain , even though these are all 32 gram cartridges , as opposed to standard 36 gram 2 3/4 inch cartridges.
