As
@FEENIX said.
What works in my rifle may not work in yours.
And due to possible litigations, I will never share a specific powder charge over an open forum.
Now if you need help with the process of finding an accurate load for your rifle, we are here.
From what little info you gave us, 7828 is a decent powder for that bullet weight.
While I shoot a lot of SSTs for range use, I find that they tend to expand faster than other bullets, to the point of too fast.
Friends of mine use them, and they work. But they get a lot of blood shot meat.
If you want to stay in the 150gr range, I'd suggest the Nosler Ballistic Tip or Berger Classic Hunter.
They perform differently from each other, but they work.
And you will notice smaller group sizes than the SST.
I have some 150gr Tipped GameKings, and they have proven accurate at the range, but I have yet to take any game with one.
