Run out

[209jones]

One of the very knowledgeable guys on this board has told me about
a possible way to reduce runout when using a Redding Competition Seater.

It turns out that the case shoulder does not touch the shoulder of the sliding
sleeve---not having the tapered case shoulder nudged toward the center.

The suggested improvement was to face off the bottom of the sliding
sleeve by a TBD amount---a questionable thing for a person with my skills.

A workaround was to remove the shell holder and put a small ceramic disk
magnet on the top of the ram.

This did allow contact between the two shoulders and make a minor reduction
in bullet runout----not tested to see any improvement on the target.

This is a small job for a skilled machinist---but---any merit here ?

To my mind that just creates a floating shellholder equivalent, same effect as a Co-Ax or MEC. Don't know til you try it, could just cut off the U part of a shellholder.
