It depends on what your primary use is.
For clays, you need to break down how you are going to build your score.
For instance, any kind of a NSCA shoot is going to have plenty of long targets to separate the 12 gauge guys shooting for HOA and punches. There will also be edge on targets. (Early battues , skeet High 1, etc)
A .410 is handicapped there because of pattern density at range.
The statistics show “Full” gives best probability on those.
But if you are shooting at a “Fun shoot”, sponsored by a club or sporting organization, they will have plenty of close targets that really reward more open chokes.
You build a score perfecting shots based on speed and distance, much the same as a pro golfer works his way out developing his putting and short game. Decreasing aiming error through practice and technique adjustments.
A chip is a scored target. Not a dead bird.
For hunting, you want clean kills at your “avg” shooting distance.
I use 2.5” cartridges in the .410 @ 1250-1300, mostly 7.5’s.
My avg shot is “skeet like”, so 10-25 yards.
Never an “edge on” target,
You can get higher 1st shot kill ratios with a little more open choke, and then mod for the second.
This is birds over dogs primarily.
You might be just fine for pass shooting staying with the chokes that get you your best clays scores.
