220 maker Rex load data

[bgblue1978]

Does anyone have experience or load data starting point for the 220 grain maker Rex loaded to subsonic velocity in 300 blackout?

I'm especially looking for OAL and favorite powders. I have 296, cfe blk, a1680, and lil gun on hand. I'm hoping to use these for hunting this year in a supressed bolt action.

I don't recall the charge, but it works well with 1680.

Thanks I'll start with 296 and 1680. They still haven't replied to my email, most likely not staffed right now. But I did find on their site they list the loaded ammo version of this as 2.185 coal in case anyone else is looking for that info.
