30 cal subsonic hunting hollow point?

Any interest in a 30 caliber RG2 or RG4 mold dropping a 200 grain or so hollow point? My intention would be to get a bullet that maximizes killing power out of a suppressed 308 or 300 Blackout. Having a relatively heavy bullet with a hollow point would help make it a more humane killer, especially if cast from a softer alloy and if the hollow point were relatively deep. In a perfect world we could get an RG4 with 2 PB and 2 GC cavities.

Any interest? There’s a somewhat similar group buy running from another maker but I don’t expect it to happen until 2016 if current lead times are any predictor.
