A question frequently asked by prospective handloaders: “Should I buy a single-stage press, or a progressive?”
Having sized, primed and charged our brass, the next step is bullet seating. Many approaches are possible; one that works well follows.

Next, back the seating stem out and screw the die down until the internal crimping shoulder touches the case mouth.
Focus on not inadvertently exceeding the boundaries of known, safe data.
