I have also had really good luck with H-380. WW760 and RL15 will usually give more speed, but those little balls of H-380 throw wonderful out of a powder measure and shoot tiny little groups in many rifles. Have you tried the new Sierra 55 g. Blitzking? Although I have had great luck with the V-Max and the Ballistic Tip over the years, this is fast becoming my "go to" bullet in this caliber.
