Do you think this NOE mold would work in a 300blk out?

118gn RG gas checked. Either an AR or bolt.

You might have feed troubles with that wide point.
Most blackouts have a fast twist which does aid bullet expansion.

I'd say no at first blush, at least in an AR. Meplat is pretty wide for trouble-free M4 feed ramp functioning.

Thanks guys! That's kinda what I surmised.
