[QUOTE="J E Custom, post: 1672951, member: 2736"] Changing from one component to another can and does normally change the SD, ES and velocity. In the example of case brands, it is a volume issue more than the brand it's self. The less the volume, the higher the pressure and velocity. when you anneal cases, even though you use the same brand, the hardness of different annealed cases to non annealed cases can/will vary. When looking for SD and es, be sure to shoot the same number of rounds for each load to get a better representation of actual numbers. simply cleaning a barrel will/can change the velocity and ES. I keep all of my brass separate buy the lot# and number of firings and brand. I never mix any components that could hurt my SDs and ES. Just because one brand is more consistent doesn't mean that there isn't a equal quality with another brand with minor changes to reach the same approximate velocities with the same pressures.
