Default Is 3 1/2" chambering needed??

Going to be taking up duck hunting this fall and I'm looking at getting a shotgun...and I was wondering if a 3 1/2" chambering is needed or if just the normal 3" will do the job. I dont have the experience to know the answer so I put it to the good folks here on the forum. Thanks in advance for any answers.

Not for duck hunting. Most bird loads are 2 3/4 anyway. I really don't know of any 3" bird loads.

Yes and no.

Is it needed, no. 2.75" and 3" were working well, especially on ducks before the 3.5" was released. Will it make it easier, yes. Especially if you target larger birds - goose, turkeys, that thing from Sesame Street, etc. It'll also help for farther distance shots. If you buy a 3" capacity shotgun, that's all you get. If you buy a 3.5", you can shoot anything.

In my experience shooting ducks from decoys does not require 3 1/2" ammo. 3" is plenty, if you can shoot. Pass shooting at range (35-45 yards) can call for the heavier payload of the longer rounds. Geese are easier with the long rounds.

All advice given is great. As too ammo-black cloud or any HIGH end fowl shot.

All of the above is great advise. The smaller amount of shot you use the more accurate the shooter has to be. I've shot alot of ducks with a 20 ga(but I missed alot also). So 2-3/4" or 3" or 3-1/2" is really up to you.

I've read that using a shorter shell than chamber length allows room for the crimp to open fully, resulting in a more consistent pattern. This prevents a slight deformation of the shot as it is squeezed past the crimp if the shell is the same length as the chamber.

Depends on how tight the chamber is and the brand/type of shell being shot.
