Beginner .308 reloading - where to go next

[Caseknife]

VLD reamer in the case mouth makes a huge difference in seating monos

I plugged your 24" barrel, 2.800" COAL and 150gr CX into QuickLoad... If you are willing to consider alternatives to the Winchester powder you mentioned, and want a highly efficient load with as much speed as possible (ie. monolithic bullets), I'd look at these three powders first:
VV N530 (may be difficult to find)
AA2520 (aka "Camp Perry Powder")
IMR 8208XBR

-OR-

Follow the advice of the guys at Hornady: "If you can shoot Varget, shoot Varget."

Re. seating depth and a load for shooting game at typical distances... not a rabbit hole worth exploring IMO, especially in .308. Seat your bullet of choice 5 thou under your lands and look your node. It won't take long to find what you are looking for.

Have fun!

As others have mentioned, 130 TTSX is the way to go for a mono in a .308 Win.
