......and my Vortek HW80 spring broke yesterday. I bought the .22 cal. gun new in Feb. this year. Put 500 on the factory spring and seal before switching to the Vortek spring and seal. I expected to get longer life but no complaints. Broke clean about eight coils in at the end of the spring guide. Have the factory spring back in while waiting for another Vortek replacement. The factory spring feels considerably easier to cock than the Vortek. I love this HW80.
