IME, TiteGroup burns pretty hot and I've had issues with leading when trying for anything close to max loads and cast bullets while using it. Start low and stay low, there are better powders for medium cast loads.
I agree, treat TiteGroup like you would Bullseye, it is a little slower according to the burn charts but I don't have a lot of faith in burn charts when you can download from three different sites and all three charts are different. They are just a general guide to me.
If you want medium loads, I would use either Unique, or Universal Clays, I prefer Universal but there are a lot of other powders that work just as well.
Just my opinion.
