Tom,

4350 is a tad slow for 168 hpbt bullets. Varget or 846 are better choices. My experience with Varget was not good, I couldn't get it to group tighter than around 2 minutes in my Savage 10 Tactical, at least within the published starting and max charge weights.

I've never used 846 as a reloader (although I've shot plenty of ammo powered by 846).

I recommend H4895 or IMR4064 (one of my standby powders). H4895 will be a tad more temp stable, but the 20fps spread I've seen reported for IMR4064 is very good as well. Although Fed GMM used to be powered by 4064 (don't know if that's still the case or not) so you might want to try H4895 first.
