If you don't mind fooling with it the GRT software works really well and is free for download.

Unless it’s a European powder the models are not there or pretty inaccurate

I guess I've had better luck than you have. Most of the powders I've used match pretty well, including IMR, Hodgdon and Accurate powders. Plenty of bullet selections as well as being able to input custom bullets.

I worked with programming internal ballistics programs many years ago. It is not something that will give you exact results. Getting better than 10% variance is excellent results. You may get that by changing lots of powder or swapping primers.
