I ordered the exact same ones as you did (I believe they're new in the white) but they haven't arrived yet. My last 3 were the same and they were great. Panaceabeachbum re-chambered them and I MADE THE MISTAKE OF SELLING ONE duh. So I have more on the way
There are three 7.62x25 threads on this page:
Be sure to check out Dvann's thread "For my next trick......."
7.62x25 threads are everywhere - I just completed my first MG47 in x25, first fire was last night
Try AKfiles.com and do a search in "Gunsmithing and Build-it-Yourself" then try Gunsnet.net 7.62x25 is definately the cheap hot little caliber to experiment in
