Lee Precision rocker LM3239 for Load Master press

Lee Precision rocker LM3239

The LM3239 rocker is the oscillating arm of the priming system for the Lee Load-Master progressive press. It picks up the primer from the chute and brings it to the priming punch, which inserts it into the primer pocket during the upward stroke of the carrier at the second station of the press.

It is one of the key components of the on-press priming system: if the rocker is worn or deformed, the primer may arrive tilted or not arrive at all, resulting in crushed primers or skipped stations. Lee Precision catalogs it as a Load-Master spare part with one unit required per press. The Lee Load-Master progressive press operates on five stations with an automatic 72° shell plate rotation at each lever cycle. Lee Precision moved the platform to legacy status in April 2022, but spare parts remain in the catalog for those who continue to use the press.
