Ok so practically every shot is a failure to fire. And I just bought this gun about 1.5 months ago. Looking at the pin strike on the cartridges, it is very weak and not prominent. But I dont think its a firing pin issue or any spring issue. When closing the action the bolt is not tight. there is some play in the bolt. Let me give you an example... I shot 5 shots normally and every shot was a failure to fire. Then I decided to push on the back end of the bolt to try to keep in in place while shooting... shot 5 shots and not one failure to fire.... This problem is driving me nuts and any input would be appreciated but I have a feeling im going to have to send this lemon in for repairs. Let me know if you have any insight... I also made a video of the example I provided above, let me know if your interested in seeing it. Thanks in advanced Mossberg owners.
