MP842 powder

Does anyone have any experience with MP842 from Midwest powders? They say to use load data for WC 842, but even that is pretty sparce with mostly conjecture on various forums.

I’m reading that it’s somewhere between H322 and CFE 223, but can’t find anything concrete at all.

It’s going to (hopefully) get loaded into 223 under 62gr soft point and steel core, and some 75gr HPBT of I can find some data that’s trustworthy.

Can anyone point me in the right direction?

Thanks

I haven’t used any, but what I’ve read before is that most people use H322 starting data and work up from there.
