I've been using this same setup since TK first came out with the DoubleKross mags. I used to wind 1.5 turns but switched to 2 turns a couple of years ago. I live where I can shoot almost every weekend of the year. some weekend 2 matches. I shoot a lot and I have TK mags that are still the original style. These mags run flawlessly in my VQ guns, and last for years. I know that some of my mags are 8+ years old.
