Received these today from CMP sales. 10 standard GI 7-rounders, dated 6/30/1992 still in the factory packaging. I believe these are Checkmate manufacture (CAGE Code 1M291). Set me back $86.95 shipped, so not too bad for a batch of range/plinking mags.
Presumably these aren't reliable with anything but 230 grain hardball?
