3...........These days ($$$), I take a quick look at QuickLoad, and manuals, and pick the best Hodgdon powder that nearly fills the case and delivers top velocities, the appropriate CCi primer, the correct type and weight of bullet for that rifles intended use, 1 Hornady, 1 Sierra, and 1 Nosler. If tweaking charge and seating depth does not do 1" at 100, that rifle makes a hasty retreat, and I start with a new rifle.
