I used to use Varget with 168/175 SMK's until I couldn't find any a couple years ago. I did find some IMR4064, and my Savage 10 shoots it really well. I can't recall what my charge weight is for the 168 or 175 SMK, I just did an OCW testing and found what they both like. POI is identical for both and they will easily stop a coyote.
