Allways start low and work up.
I have the 6 edition, {2003}, Hornady manual. They state that Hodgdon's "Varget" and IMR's 4831 gave best results from there 23.75" barreled Win model 70 w/1:10" twist.
With todays controlled expansion bullets, with thier thicker jackets and harder cores, pressures are will be higher than with "conventional" bullets in some circumstances, start low and work up!
Using 165-168g HORNADY bullets, the HORNADY manual prints:
Varget--Starting load is 41.4g for 2400fps, and Max is listed as 49.4g for 2800fps.
IMR4831-- Starting load is 50.6g for 2400fps, and Max is listed as 59.5g for 2900fps.
Don't take my word for it though, a reloading manual for your cartridge can be bought for less then 10bucks!!
