[QUOTE="Michael Courtney, post: 683857, member: 28191"] I've found it much easier to load for low velocity variations in most of the shoulder fired rifles I've loaded for than for the barrels in universal receivers. This runs counter to my intuition. But my experience is that good case prep, careful powder selection and measurement, selecting a quality bullet, and a good barrel cleaning routine are all that is needed for load consistency in most of my shoulder fired rifles. Universal receivers and rifles held in a ransom rest are a different deal. I would have though adding effective mass and/or tightly coupling the rifle to a shooting bench would be an advantage to consistency. I think perhaps there is a reason why the reloading manuals do not report standard deviations or extreme spreads along with their velocities. [/QUOTE]
