I’ve surfed the web looking for 6.8 loads with Win 748 as thats the only powder I could find at the time. I’ve included the loads in this post. I’ve only tested 29 grains in a 120 SST bullet. However Ive found the load consistently hits high and right vs factory Hornady rounds. I’ll keep looking for some H322.
