thanks,

from that pics you showing.. the one upside down.. I noticed on the bottom got a slight ring.. the other spent case.. got a ring ( the middle).. tell me I am right or wrong.... this something I am watching for but never knew what to look for.. I always track the amount time the brass case get reloaded.. after 5 or 6 times.. it goes to the brass recylce bin.
