120-123's I like AR-comp.
For lighter, 100- to maybe 120, 8208 xbr. Have to be careful in the 120 class with 8208 however, it can spike quickly up around the 28.0-ish max book loads. Still lots of guys use it for them successfully. Work up loads for your barrel, don't just jump in at max.
You don't say what barrel length or type you're shooting. For some bolt actions you might be able to use a longer Coal which will possibly reduce your peak pressures.
Also, what is hot and what is cold.... if you're loading at 79* and temps go from 40-90, not much effect imo on hunting distances if you're on a good node.
1Shot on here uses the 120 pro hunter, deer-slayer in his neck of the woods.

Have you bought the Grendel hand books, vol 1 and 2, they have lots of info and loads in there. In the vendor section on here, AR15 build box website.

Indispensable for the Grrr.
