As examples, both my 338 WM and my 30/30's love that powder and even loads as low as 30% ignite nicely without fillers. The downsides are is that it is expensive and often very hard to find so I developed alternative loads that shoot almost as well usually using RE-7 which is more reliably available. Another thought about cost is that even though it is expensive, you will use a lot less of it evening out the cost.
