Anybody know what CS means. There is what looks to be an 8 written in pencil laterally above the C.S. The head stamp is the typical Remington Express 12 ga with a copper colored primer.
Someone suggested chilled shot. Makes sense but any definitive answer?
Anybody ever seen one before?
I am selling it and would like to have a fair valuation
I’ve seen thousands of paper Remington shells and have never encountered one like this
