I have gone up to 45grs with ok accuracy but I get better results with N-550 when using the heavier bullets like 190-220 , I think its due to the Varget filling the case to much.
 
Like James said I would personally use a slower powder with the 190's. If you like hodgdon powders consider using 4831sc for that heavy of a bullet. I get excellent speed and accuracy with it.
