[QUOTE="Hiwayman92, post: 1165554, member: 85098"] Just got my build done, and I'm working on building a load for the 175 ABLR. H1000 seems less accurate thus far, but more consistent velocity. I'm trying to wrap my head around why h1000 has a 50 fps velocity range, and 7828 is giving upwards of 100 fps, but is still grouping 1/2 minute at 100 yards without attempting any fine tuning with seating depth yet. I've deburred the flash holes, and properly prepped the brass. What can I do to get more consistent velocity? This is my first day with a new Caldwell chronograph, and by the end the old 9v battery was dying. [/QUOTE]
