St. Marks OPB 244 gunpowder

Does anyone have personal experience with St. Mark's OPB 244 gunpowder? On the jug it says to use "Titegroup" load data. In searching the powder itself there is very little data. From what I have learned from the internet is that St. Mark's (a General Dynamics Ordnance and Tactical Systems company) is a commercial powder and has a burn rate that is faster than my current powder of choice, CFE pistol.

Any help will be appreciated.

WOW, nothing but crickets!!! :D I was hoping someone had experience with this powder to give me some insight on how it performed. I guess I will leave it alone due to it is in a 4# jug and no primers to expend to set up a load.

I had the same problem with BR5, " Similar to Unique " Military surplus over stock for 9mm loads.
Can find "NO" info on manufacture, Mfg dates, mfg ?
Found a little bit of load data, not much?
No primer to spare for work ups?? But, at least I have 6# of it on the shelf.
