Well, it seems if you look at the next smaller cal. ( the 270 roy) you will have start data in this case. There are some 270 stw shooters here that'll be able to get more specific but I've had to do similar with the 7rem/7stw/7rum on a few occasions.
Example: With the 7 rem and a 140, 68-70 of rl22 is tops; and it's a start charge in the 7stw. Be very careful as it is a rather rough approximation.

I may be off but it seems like 59a or 60a grains of h-4831sc would be a decent starting point.

Hoping some comes in saying to use 7828 retumbo or h1000 I have plenty of that. I hate working up loads on a gun like this it always make me nervous. But I'm also thinking of finding a good load now and redo it in the summer when pressures are different. Our doe season here doesn't end till march 30th so hoping to tag a few with it this season
