ive had some bad luck w/ wolf 62gr (a case i purchased cheap a couple of years ago). i found it odd that it chokes an ak, so i started inspecting the cartridges better as i loaded the mags......i noticed lots of instances of split necks, long necks, inconsistent neck crimps, shaved jackets/jacket bunching at the case neck, etc.....seems that this lot had no apparent QC before it left the factory, or maybe it was a whole bunch of rejects packaged for quick/cheap sale.....kinda turned me off to wolf, and i stick w/ silver bear now.......seems you may have the same probs i had.
