I don't have a "standard" load....a lot depends on where/what I'm hunting, and what shotgun I'm hunting it with.
My main gun is a Remington 870 express, and if the quarry is ducks over decoys, then my "standard" load is 1 oz of #3 steel at 1450-1500fps (handload). I've dropped a lot of ducks with this load since I've started using it, and I use it probably 85-90% of the time.
If I am using my older shotguns (Mossberg 500, Remington 1100) or my Remington O/U, then I'm usually shooting 1 1/8-1 1/4oz of #5 bismuth (ducks) or 1 3/8-1 1/2oz of #2-BB bismuth handloads (geese).
If I'm hunting geese exclusively, I'll use either factory Federal tungsten iron (3") or handloads of 1 3/8oz #2 hevishot handloads.
In my 16 gauge shotguns (Remington model 11, Ithica M37), then it's 1 oz t0 1 1/8 oz bismuth #5 or #6 shot (handloads).
