300aac blackout

All the powders I have seen used for loading 300 BLK are also used for loading .410 shotgun however my go to powder for .410 is Alliant 410. I'm curious as to why no data using it? Checking burn charts it falls right in there amongst the powders used and is so much cleaner burning and better metering than H110. I quizzed Alliant for data but they only recommended 2400 recipes which falls right beside 410 in the burn charts and provides much lower velocity than H110 or LILGUN. Thoughts, experiences? Thanks.

Labwork costs money. The 300 BLK is relatively new, so there is not a lot of tested data yet.
