Have not tried it, and nobody I know personally has yet either.
Their page says similar to RE-15, but it is pull down from a cannister grade of Rheinmetall-Denel (RDM) S341
Here you will find load data: https://shootersworldpowder.com/data-table/
Keep in mind, the stuff you will get is pull down powder and you will need to do your load work-up carefully to see how your batch behaves compared to any other data you find.
I am going to give it another shot next month .
I loaded 20 and am not impressed so far .
Hopefully others might chime in ?
That was with 109's , I am breaking in a new barrel now so may load some 90 eld's for giggles ?
I haven’t had time to load it yet. I will probably do it soon on 6mm creedmoor. My rl16 is almost gone so I need a new load. My dasher shoots too well with varget for me to waste barrel life doing a work up on something that I can’t imagine shooting better than the varget.
