Was out shooting my mkiii yesterday and opened a new box of federal American Eagle lead round nose and I experienced several hang fires and rounds that sounded like I quiet puff which fell short of my 15 meter target. I checked for a squib every time I experienced a quiet puff and when it didn’t cycle the action and sure enough I got one squib. I have never had issues with federal .22 but this was bad. Sometimes almost two seconds after I pulled the trigger the round would go off . I contacted federal via email to seee what they say. Lot # was 2rp133
