If I were you I’d load 1/2 grain more of each load, and 1/2 grain less of each load, as well as replicate the posted loads again, and go shoot some groups with those 6 loads.
Then I’d try the best looking groups again, and yet again at 300 yds.

Did some more load testing yesterday. The half grain increased load for the H4831 worked really well.
Also tested Hornady 120gr HP over top H4831 as well, which performed really well.
The 50 and 50.5 gr loads of H4350 were the last loads I shot that day and I think I was rushing them, hence the crappy group @ 1.3". I think I could tighten that up quite a bit.
Next tests will be 5x 5 shot groups of the loads in the photos.
