Back in business ?

[Zazu45]

Hi guys.

About 15-20 years ago, I kind of been forced to drop shotgun hunting. You know: raising kids, factory closure, house payements...
Anyway, even ended up having to sell my 12ga. Browning BPS and reloading equipment.
But finally my life is getting back on track(touch wood) and the hunting bug been after me this fall.

So here goes, seems it is a whole different ball game these days?
I been looking at buyng a shot gun lately and have bee hearing all kind of stuff about what works and what does not.
Some say nothing short of a 10ga. for ducks and geese,
others say a .410 is better than a 12ga.3.5 and others claim hardly any difference betweem steel and lead.
So see I been looking at getting A Remington 870 3inch .
So what's the truth about steel shooting?
What works and what does'nt?
Wich brand of ammo and what shot sizes work best?
Is Winchester :Xpert, SuperX or Supreme any good, that's what the easiest to find in my area.(Quebec)
I hunt mainly along rivers, irrigation ditches and small swamps,
mostly pretty open spaces and range tends to vary alot, also there is always the odd goose that fly by.

Thaks for any help.

Denis.
