Maybe this will help some as a guideline to where burn rates apply to different bullet weights. As always this is a guide, you must test in YOUR gun. Start low and work up as with any load development. These loads have been shot in Savage ML's. I do not know how that compares with the ULA. I do know that some are real rompers & stompers in the Savage.
