Anybody have any hints or tips for success with shooting the 247 in subsonic loads? I have the RG4 version, so mine are hollow points if that makes any difference.

I seat mine to the top of the last driving band and they seem to feed fine in all my rifles/pistols. If you are looking for an easy starting load, try 10 gr of 1680 powder and work up or down from that. I also powder coat mine to avoid using traditional lube with my suppressors. What particular issues are you having?

I just can’t seem to find a subsonic load that will group well. I’m sizing to .310 and have tried a few different powders and lubes. So far most have been air cooled COWW.
