Green Dot is a great powder for 3/4 oz 20 gauge loads. Depending on if you need to cycle a semi auto, load it down as low as you want to reduce velocity and recoil. I load some around 12 grains of Green Dot for around 1100 fps. They are a little dirty, but very light shooters for the little guys. If you are getting a too dished crimp, get some ClayBuster 3/4 oz wads, or throw a Cheerio in on top of the shot. Mark
