I just received a PMA neck turning tool with a 22 cal. neck turning mandrel. How loose of a fit should there be between the outside of the neck turning mandrel and the inside diameter of the case.

Measured O.D. of 22 cal mandrel: 0.2015”

Measured I.D. of Resized 223 case: 0.2215”

0.02” seems loose.

If I use the 22 cal expander mandrel it increases the clearance even more. The expander mandrel measured 0.2220” outside diameter.

Thanks
