Reason I wrote that is once a friend and I had been shooting .22s. He racked the bolt (semi auto) once, and nothing came out. He then pointed it out the window, pulled the trigger and POP! YUP, for some reason the extractor didn't grab the round. Ever since then I ALWAYS rack the bolt, slide or what ever 4 or 5 times AND LOOK INSIDE THE ACTION!
