Barrels are funny things. With at 1:9 twist you are on the bare edge of stability for anything over 69 gr. One 1:9 barrel might not even stabilize a 69 gr, while another one might stabilize up to 75 gr.

The only way you will find out if your particular barrel will stabilize 75 gr bullets is to buy, a 100 load them up and see what happens.
