Daystate Howler slug velocities with Red Wolf .22 HP?

I am curious to know what velocities have been tested by the ART Team with the .22 HP Redwolf? I don’t have the Heliboard or DS Programmer but I would like to know users experiences / testing on high, medium settings.

My Safari shoots the MRDs at around 970 FPS on medium power. I’m going to buy some but was curious about the testing and what power settings and velocities were optimum. 

Thanks
