My buddy has one and I did all the load development for it. Tried several powders eventually settled on h4831 ssc with 140 Sierra’s. Magpro gave phenomenal velocity but chit groups. I also bedded it and did the false screw thing like you did to yours as well. With this particular rifle once I got over 2800 plus the groups opened up. I don’t know if it was just a shot out barrel or what. He had bunch of ammo that came with it, most loaded up with 100gr bullets. Which made me wonder if the previous owner took it prairie dog hunting 🤪. I love to find one, I had one yrs ago and was talked out of it. .
