I found these cartridges that my nephew left at my house a few years ago. I believe he thought that they were for his dad's old British 303. They clearly don't show 303 on the base. I think what I'm seeing is L C , 6 6 , MATCH, and what looks like a circle with an X in the middle....it's a VERY tiny mark, so I'm not 100% sure on that one. Diameter, and shape is almost identical to a .308 cartridge. It is about 1/32" shorter than the .308.
Does anyone know what they are?
