Shoulder set back.

In a recent discussion of the use of an RCBS precision mic for determining shoulder setback when resizing cases the question of what does one do once steel on steel contact is made between your shell holder and the bottom of the sizing die and you would like to have more set back.

This was my response.

The RCBS Precision Mic has been a very useful tool in my workshop. I often use a know good headspace gauge to confirm readings. Being from the " old school" I still believe in using the correct tool for each purpose.

If you are getting to the steel and steel contact and are looking for more setback, Redding makes shell holders of varying depths for that purpose. Works great for my precision ammo when stock shell holders don't get the job done without modification.
