Lee Precision Decap Mandrel .262 for 6.5 Creedmoor and 6.5x55

Lee Precision Decap Mandrel .262" – 6.5 Creedmoor

The Lee Precision Decap Mandrel is the decapping spindle for Lee collet neck sizing dies: it is the element against which the collet fingers squeeze the case neck, and, at the same time, it carries the pin that ejects the spent primer. This .262" version is the one specified by Lee for 6.5 Creedmoor, 6.5x55 Swedish Mauser, 260 Remington, 6.5 Grendel, and 6.5 PRC, and it should be replaced when the pin bends or the mandrel becomes worn.

In the collet die, the neck is not compressed by an outer ring and then opened back up by an expander, as in full-length dies: four fingers squeeze it directly against the mandrel, so it is the diameter of the mandrel that determines the final internal measurement of the neck. For this reason, Lee makes the mandrels .002" to .003" under the nominal bullet diameter: with a brass spring-back of .001"–.002", the finished neck remains approximately .001" under bullet diameter, which is the correct tension to hold it. Lee describes this system as being capable of producing a precisely aligned neck, reducing runout.
