I have gotten higher velocities with IMR 4831 than H4831sc with all 130’s! Mentioned previously that I have been using R17 with good results. Using R17 because I bought too much when it was being touted as the “new wonder powder”.
These days I prefer owning cartridges that have many good to great options powder wise. I see the sad faces of those who can’t find Retumbo and am glad I am not one of them.
