You might consider the Nosler 125 ballistic tip. I have been very happy with them, and they are readily available, though a bit more expensive than the SSTs.
Theyre dang near twice the price of SSTs and have a much higher expansion threshold than them as well. I like the speer tnts better for my secondary bullet. Flat base bullets work better for the blackout in my experience. My main bullet these days is the 110 varmageddon since its cheap and very accurate out of my 9 and 16 inch guns.
