Any experience with Midwest Powders MP605 in .300 Weatherby?

Since IMR7828SC is nowhere to be found and Hybrid 100V is, likewise, unfindable I ordered some MP605 from American Reloading. It claims to be "similar to Hybrid 100V" and the only reference load they give is within the range - for 6.5 Creedmoor. I'm OK with extrapolating for the Weatherby based on Hybrid 100V data but I'd like to hear from anyone who has already blazed this trail

I picked up a jug of that some time back. Never got to try it as I still have some Hybrid 100V yet. The label is worn but basically it states start under 10% of Hybrid 100V data.
