Glad to hear that! I usually use #5s for teal then bump up to #4s for big duck season so I’ve never tried the smaller shot sizes on any ducks. If I have the same results you’ve had, I’ll be stocking up as these shells were only $4 a box when I found themEXTREMELY WELL!
I've been shooting 2 3/4" 1oz #7 super x steel at bluewings all season and will not be buying anything but that for teal going forward. Teal are "trusting" and I've never had too much problem getting them to commit to a spread. I usually toss 12-24 decoys with 1-4 spinners right in the middle. Furthest decoy is maybe 30 yards from where I hide. My hit rates went up when I started shooting a cylinder choke and smaller shot. A buddy of mine hand loads #8 bismuth and I can tell you I kill just as many or more birds as he does hunting side-by-side and don't really have cripples.
I've been impressed enough with their performance and cost (like $30-40 for 100) that I'm going to try them on wood ducks this year too. I duck hunted almost every morning last year and have made all but 3 mornings of teal since the 11th so I appreciate a cheaper (and easier-recoiling) load.
