Just tried some in my Norinco NP22 (Sig P226 clone). Will not extract reliably in a gun that otherwise works flawlessly. The manganese coating on the steel cases makes them very dusty and rough feeling. These are nothing at all like a typical lacquered steel case. These are more like they are parkerized, minus the oil. At most I could fire off two rounds before a failure to extract. After going through 10 rounds, I decided to quit before I damaged my extractor. Its also very hard to load into the magazines. The cases are so rough and dusty textured that I can only push 6 or 7 rounds into a magazine before it jams up tight.
I will find out what Cabelas return policy is soon. I see from the online reviews on Cabelas website, the majority of users give it the lowest rating possible, only 1 star.
I also filled out a complain on Winchesters web site. It will be interesting to see what their response is.
