7mm RM h1000 160gr accubond load suggestion

I already have a lot of h1000 powder for my 300 wm and I'll start reloading 7mmRM for my brother in law this fall. So I don't want to purchase another powder for someone who shoot less than 20 round a year. Our bullet of choice is the AccuBond so in his case we will load 160gr bullet in Nosler case and Federal 215m primer. But on the website I only see h1000 for heavier bullet in 7mmRM. Can you tell me on your testing which start and max load I should use for developing the load. Thank You

According to Hodgdon's posted data:

63gr-66gr of H1000 for the Nosler 160 Partition. That should at least get you started in a safe area.
