shot410ga..... I have to go with Coach on this one....While Green Dot is a viable 1oz. powder, it is not the best choice for them. Burns much too slow and is much too dirty in a 1oz. load. Green Dot is primarily a handicap 11/8oz powder, and performs best when used as such. There are several other powders available that will give you better performance for 1oz. loads, as well as a lot more economical. REX I or Promo come readily to mind. Of course, Green Dot will work fine for them, but, in my opinion, it's like using a 30-06 to shoot rabbits. Will work just fine, just not the ideal choice.... Just my experience.... Dan Thome (Trap2)
