I have two powders I go to on that load H1000 for accuracy and Retumbo for velocity. Have tried them all for many years except some of the new Enduron powders. I’m in Colorado so must have a non-temp sensitive powder. I shoot in climates and altitude from 90 F to -15 F and 4,500 ft to 11,000 ft. Found those two powders to be the most stable and consistent of all of them in those conditionsLooking to shoot 180 grain pills out of 28" barrel.
Was going to see what the consensus was.
