As you probably know, Green Dot is at its best with 12ga 1 1/8oz handicap loads. I'd look at the 1 1/8 oz loads on the Alliant reloaders guide, and maybe try something different. Green Dot is as good as gold right now, you might be able to make a trade for a powder that would work better for 1oz loads in your 16ga. Alliant does not list any 1oz 16ga recopies in their data. Some trap shooters use 12ga 1oz green dot loads, but I feel its rare as green dot is in such high demand right now for those handi loads. There are so many better options for 1oz, 700x, promo, clay dot, Red dot...etc. I wish you luck!!
