So today in Canadian Tire in Leduc i saw cases of Chinese 7.62X39 1440 cases listed as non corrosive. Green Box with two tin cans in side. The Chinese card intop of the spam can said it was made in 71 so I'm wondering if it truly is non corrosive or if they are pulling a fast one. I did purchase a case and just am wondering if it is or not in case I need to do extra cleaning after using it. I can post some pics of the crate if need be.
