Not sure how i missed this, but have hunted Weldon Valley many times. Always seems to be some ducks thee no matter when I have been. I have had some great days there before. you will also get some geese in there from time to time as well. Good dove hunting too.
FYI... word to the wise ...Get there early and set up in a good spot as the boys sure like to get there early! This year there has been some teal there everytime I was out dove hunting, along with some gadwalls and shovelers./spoonbills.
What does "gauge" mean anyway? As used here gauge means the number of round lead balls the same diameter as the inside of the barrel (aka the bore) that it would take to weigh one pound. It takes 12 lead balls the same diameter as a 12 gauge barrel to weigh a pound. The smaller 20 gauge would require 20 balls of that barrel diameter. The larger bore 12 gauge would require 12 lead balls of the bore diameter to weigh one pound.
In general the number of pellets in a shotgun shell...
