Worked very well for mine using 100 grain bullets. I notice that some recent manuals are very conservative with charge weights.

Hodgdon's website has load data using H4350 for bullets weighing from 75 grains to 120 grains.

For decades, IMR4350 was the go-to powder for the big .257 and was listed in the Weatherby Reloading Guide. Today there are more suitable powders available which will give higher velocities with most bullets, but few will ever notice any difference in the field.
