Certainly plenty of special load data is out there for Ruger #1 rifles and Marlin .45-70's and so on. Some Ruger revolvers in .45 Colt seem often to be loaded to .44 Magnum pressures.
The thing to watch out for in all this is how heavy the revolver is? Elmer Keith developed the .44 Magnum in .44 Special large frame revolvers that had enough steel in the cylinder walls and heavy enough frames for the task. Typically that kind of work up was done by inching up a load of 2400 a fraction of a grain at a time until fired case extraction got sticky from the chamber walls expanding too much, then backing the load down 5%.
If the different Ruger cylinders and frames are not uniformly stronger (and I would not expect a Vaquero to be up to a Super Redhawk, for example), I'm not sure anyone will post generalized increased pressure loads for all Ruger revolvers, but rather they will be posted for specific models. You might try using the advanced search function with your model to see if anything's been mentioned for it?
