According to the 49th edition of Lyman's Reloading Handbook for the .30-06 Springfield:

165 gr. Jacketed Ballistic Tip using H380. the suggested starting load is 48.5 gr. and a Maximum load of 53.0 gr.

But like Colorado suggested, the pressure will change with different bullets and would be best if you checked the bullet manufacturer's suggested load data.

It did not list H380 for the 180 gr.

You can also go Hodgdon.com and get reloading data using their powder.
