I use the same load of H335 with the dogtowns, really haven't worked with the bergers much at all. I've got a box of them, but don't use my 204 for coyotes as it weighs around 80 pounds, lol. IMR 4198 actually worked ok with 32's and 34's also, but I only used it because I bought a few pounds stupid cheap. It's too much of a pita to load (weigh each one) to use it a lot. In the small calibers I try to stick with spherical powders so I can drop the charges in a powder measure.
