I personally go for accuracy over speed and that load I mentioned shoots extremely accurate in my rifle.
You said you have a 3 groove, is it a benchmark barrel? I hear that the guys with these barrels are getting more than published velocities. I have a benchmark on mine so that's why I'm asking. Oh and I just bought some retumbo. I hope it works. I have h4831sc, h1000, hybrid 100v and now retumbo to try. I hope one of these will work.
