158g Round Nose Berrys in 38 Special

Question for the group— I’m getting ready to load 38 special for a Henry X lever action. I’m looking to suppress the rifle soon so I want to put a nice subsonic load through it. I know some people hate it but I’m putting together a space cowboy gun.

Does anybody have experience using HP-38 behind 158g Berrys? Seems like it should be a fast enough burning powder to not cause any issues and still let me settle in around the ~800fps +/- 30fps range. I also have found a place that has awesome prices on HP38, so that sways my decision a bit as I could stock up for a LONG time for cheap.

If not, any suggestions for a different powder that would be good to suppress?
