This allows the reloader to 'feel' when the primer is fully seated and to identify any resistance that might indicate a tight primer pocket or a high spot, preventing problems before they escalate.

Compatibility Spotlight: The Perfect Partner for Lee Auto Prime & Auto Prime II

The "AP Only" designation for this shell holder signifies its dedicated purpose: exclusive use with Lee Precision's Auto Prime and Auto Prime II systems. These hand priming tools are renowned for their ability to seat primers with superior feel and precision compared to many press-mounted priming systems.

The original Lee Auto Prime, a long-standing favorite, and its successor, the Auto Prime II (which often features improved ergonomics and a slightly different primer tray system), both rely on this specific type of shell holder. When a user slides a case into the #11 shell holder and then positions it within the Auto Prime unit, the shell holder’s design ensures perfect alignment with the primer punch and the primer feed mechanism. This synergy is what allows for the consistent, positive primer seating that Lee Precision users have come to expect. This focused design means optimal performance and eliminates guesswork, leading to a more reliable and enjoyable reloading experience.
