I have a Daystate HP 30 cal & I am about to put a 177 barrel on it, if you have a 177 Hp would you mine sharing your info on the pellet or slug that you are shooting grain and FPS

Yes I have to change the probe out it all take about 5 minutesI suppose you need to change the piece that push the pellet into the barrel and seals in order no to receive the air in your face. the one in the .30 Cal should be much wider …
Helliboard I am testing NSA slugs 12.5 now getting a good group at 50 yardsI'm guessing from what you've related that it's a 177 poly from Daystate?
All I've tested have liked the JSB 10.3s @ 890 - 900, 13.4s @ 800, 16.1s @ 940 - 970.
The 13.4 Monster Redesign have not liked to go slow but seem pretty good above 900, also. Not much for you on slugs though. I had some INCREDIBLE results in brief testing of the NSA 20.2s but the 20.5s were more erratic. Just recently checked the recommended twist on these and it was 1 in 14" so MAYBE I have had them under spun. Soren has had very good results with the 16 gn Zan's and some other lighter slugs but I've not chased that side trail.
Do you have a programmer or Heliboard? That's going to be an important detail in your switch.
