What practice is beneficial for ensuring uniformity and performance in reloading?

Sorting cases by their manufacturing source is beneficial for ensuring uniformity and performance in reloading due to the differing specifications and tolerances that various manufacturers may have for their brass. Each manufacturer may use different materials or processes, which can affect dimensions, case weight, and overall performance. By sorting cases from the same source, reloaders can minimize variations, leading to more consistent pressures and velocities in the resulting ammunition. This consistency is crucial for achieving accurate and reliable performance from reloads, especially in precision shooting contexts.

In contrast, using a mix of different brands can introduce inconsistencies due to differences in brass characteristics. Interchanging components frequently can lead to discrepancies in load behavior and can compromise performance. Relying solely on automation, while it can improve efficiency, may overlook the critical attention to detail needed when dealing with various components and their specificities in reloading processes.
