In reloading, what is the benefit of using a progressive press over a single-stage press?

The benefit of using a progressive press over a single-stage press primarily lies in its faster production rate. A progressive press allows the reloader to perform multiple stages of the reloading process simultaneously. While a single-stage press requires the operator to complete one entire step—such as sizing or priming—before moving on to the next, a progressive press can cycle through these steps in one smooth action. This means that as one round is being finished, another round is simultaneously in processing at a different stage, which significantly increases the output in a given timeframe.

The design of progressive presses incorporates multiple die stations, which can handle operations like resizing, expanding, seating, and crimping all in one pass. This efficiency is particularly valuable for high-volume reloaders who need to produce large quantities of ammunition quickly.

Other options like accuracy, material waste, and cost might vary based on specific circumstances or personal preferences, but their advantages do not match the productivity increase offered by a progressive press, making faster production the standout benefit.
