I have a 7x57 that really likes it.
Have tried it the ones you name and it will work.
Some might not like it but i think it is a good powder.
Second that...when all else fails in a 7x57, try some W760 with 150-160 grainers. Good accuracy and velocity. If you're a max load type of person, I just recommend developing a load in the heat of the summer. Theory (and my experience) will say if it's safe in the summer it will be safe in the winter, but not always the other way around.
