Anyone remember Scot Solo 1500 powder?

In my quest to go against the grain and find the quietest sub loads possible that will still cycle an AR, I've tried some oddball powders.

For example, I could get 800x to cycle, but no BHO and just .2 gr could be the difference between a subsonic and supersonic load. Fail.

When I started handloading in 1999, I bought a pretty good stash of Solo 1500 for dirt cheap and I still have a bunch of it. Seeing as to how it's close in burn rate to N105 and is a clean burning, single base powder, I decided to try it. I took a guess where to start and tried 7.6gr under a 168SMK. It was really quiet and ejected the spent case, but didn't feed the subsequent round. 8.0gr cycled and sounded great, so that's a good start. More testing needed.

So two questions. Have any of you ever used Solo 1500? And is N105 a single or double base powder?
