Mine loves 36.5gr of IMR-4064 with the Hornady 100s.

35 gr Varget with a 95 gr SST. Maybe back off a little for the 100 gr projectile.

I'd start with IMR4350.

looked in hornady Manuel they have a load listed with h 4831,I have some of on hand I use for my 270. if that don't work I will try yals loads that's folks

Loaded mine with IMR 4350. The further I worked up in charge weight the better they shot.

Just finished some fairly extensive testing with that bullet. 41.2-41.8 gr IMR 4350 all gave me good accuracy. Velocity started to drop after 41.8 in my rifle; time to back off!

Also got good accuracy and higher velocities with the new IMR 4451 up to 42.0 gr.
