I have been loading .44 Magnum for nearly 50 yrs., my load for my Ruger 77/44 was a Hornady 240gr. XTP over W296/H110. My go to revolver load is 7.5gr. Unique with a 200gr. RNFP cast bullet, a load that is accurate and pleasant to shoot. If I wanted a load with more oomph I increased the charge to 9.0gr. of Unique.
