neck that to 6mm for my CZ 527 would be killer,,probably need the 7.62x39 mags,,
The 7.62x39 has a lot more "slope" to the case which is why the mags have more curvature and the base is .440, I don't believe they'll workneck that to 6mm for my CZ 527 would be killer,,probably need the 7.62x39 mags,,
Having a hard time digging up the Winchester Olin 224 E5 ( Experimental) Print which was designed back in the early 1960's. That is what this NEW case is. Its almost a direct copy of the 1960's Case that was being experimented with for the then new M16. Rebated and rim and all.
Nothing is Really new. LOL
