Volume 10 Hornady book.
H4350
Minimum is 58.0gr @ 2600 ish ft-per second
Max in Red is 67.9gr @ 2900 ish ft-per second.
They say that the best "normal" results for the "heavy bullets" for 300 Win Mag is RL-22 or IMR 7828 for cases that size using a 25" too 26" barrel.
H-4831 is also shows good results in larger cases,,, it is a bit slower burn rate then H 4350.
My old Weatherby Mag liked this powder.
All the above powders suggested will work good for the 178gr bullets on up.

Edit added: If you are ever planning too shoot the medium size bullets from let's say 150gr, 165,and heavier too the 200gr ish then H 4350 fits that category better than H-4831.
If your plan is too shoot 178gr on up too 225gr rock chuckers and never return too the medium lighter bullets,,, then one might stick with H-4831.
Just putting out some ideas for you to choose from.
