NOE just finished a run of their 300 blk bullet mold without any lube grooves (designed to be coated with HiTek or Powder coat). The RG version comes with multiple hollow point pin options. It is available now here:

And they included a load data sheet here:

My guess is that 10 gr of A1680 is going to be a good starting point for subs--need to work up or down from there.
