I like RED DOT, to be sure, but never found a great deal of use for GREEN DOT. It was not as versatile as Unique, nor economical as Red Dot. I used up what little Green Dot to which I had access, and never looked back. I didn't DISLIKE the powder, particularly. Just never saw it as being a "best fit" for my purposes.
If they re-vamp the production process for Red Dot, so they can make it cheaper, I wouldn't mind much if they made it just a little more fine-grained, and a little more clean-burning. Whether they do or do not, I'll probably STILL use Red Dot unhesitatingly in my future handloading ventures.
