The problem with too slow powders for a particular cartridge is they don't always light-off so consistently. While not always the case, there can be the issue with some of those combinations of pretty high standard-deviations in velocity, and associated accuracy limitations - on top of the poor velocity.
That, and 6.5 CM burn-rate powders tend to be hard enough to come by reliably, that it's kind of a waste to burn them up in a sub-optimal combination like Grendel. Just my opinion.
