Was picking up my brass after shooting Sunday and found an odd ctg. case that I never saw before and do not see in any reloading manuals I have.
It appears to be made from a .223 case as it has a LC 69 headstamp.
But the head dia. is .355
Overall length is 1.297
Head to shoulder is 1.00 with a fairly sharp shoulder.
Length of the neck is .187.
Neck diameter is obviously for a .223 boolet. Any ideas as to what it is?
