Finally got it out to put some rounds through it and my bud shot a little vid clip. This was a starting load using a Hornady 300 gr XTP Mag bullet over 28.2 gr of H110, Starline cases , and Winchester small rifle primers. Recoil was stout but manageable. Not sure how much more I would need lol but will continue to do a little experimenting. Be aware that there is some "enthusiasm" in the audio.
