Archived [ARCHIVED THREAD] - 300BO and AA5744

Has anyone tried this combo? I had powder and 168 SMK on hand so I loaded some test loads up but haven't had a chance to try them. I'm just wondering why I never see this powder mentioned even though there is plenty of load data for it.

I tried this powder with 125 grain Speer TNT.  It fills the case almost completely for light bullets (it is an extruded powder).
While working it up, I went from no pressure signs, to a moderately flat primer at .2 grains higher, to a blown primer another.2 grains higher.  

Accuracy wasn't great, but I plan on playing with the seating depth quite a bit more.

The standard abbreviation for 300 blackout is actually 300blk.
