Last fall i hunted the early teal season in MN.
6 hen mallard floaters and 2 spinners. 2 passes by the same flock and 5 shots I had my limit.
2 3/4" 1 1/8 oz #6 steel.
We don't get a teal only season here in SD, but we get to add two bonus bluewing teal to our daily limit for the first two weeks of the general waterfowl season. Most opening weekends the majority of our limits are BWT, with some mallards and pintails mixed in.
Drove through the area I do a lot of duck hunting here in SD, teal are really starting to get grouped up, I'm sure many males are already moving out.
