Lee Precision large primer trough assembly red for Load Master press

Lee Precision large primer trough assembly (red)

The large primer trough assembly is the primer chute unit for the Lee Load-Master progressive press for large-size primers. It carries primers by gravity from the reservoir to the priming station and presents them one at a time to the punch as the carrier rises. The red version identifies the large size.

This is the third generation of the assembly, introduced by Lee Precision on October 27, 2011, to eliminate recurring damage to the primer slider and the trough cover. The unit is supplied assembled and includes the primer slider, primer lever, 6-32 x 1/4 screw, and O-ring, replacing the four separate components LM3252, LM3247A, LM3247B, and LM3251 of previous versions with a single spare part. The Lee Load-Master progressive press operates on five stations with an automatic 72° shell plate rotation at each stroke of the lever. 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.
