Just picked up new 480 Ruger with 9.5" bar, has anyone tried Vitavouri powder with a 325 Gr XTP, or any other bullet. I have been using that powder in 44 mag, and like it, but do not know where to start with the 480. Any help appreciated in working up a load. I have all the data on other recommended loads, just wanted to try some new ones. Thanks a bunch!!! Doug
