My current load data is 45grains of H4831SC. OAL is 2.825 just in the lands. One ragged hole! I have shot this out to 700yards in (low wind conditions) very accurately. Speed was right at 3100 fps. I started to see some pressure signs around 46 grains. I just happen to read a post where a guy had this flavor of powder laying around and wouldnt you know, turns out it is just what a guy needs. I hope this helps you out. Good luck and keep me posted on your results.
Group below is 3 shots at 100yards
