I can tell you that the 25Bullberry doesn't love the LVR powder. And in fact, I've found apparent pressure spikes in the 30-30 AI. It seems to be specifically designed to work well with slope-shouldered cases of a certain capacity. And even then, it's only listed with certain bullet weights. It's tricky stuff. For cases with extra capacity, there are powders- Varget, H4895, maybe CFE223 - that will equal the performance without hitting a wall and spiking.
