Re: shotgun shell ejection problem
Either loose or broken ejector plate or missing/broken extractor claw.. The mossberg bolt has 2 claws so it would likely be the one on the ejector plate side. Other than that, ensure youre using the proper length shells, i.e. nothing longer than 3" and also that youre cycling the action with enough authority for the ejector to kick the shells free of the action.
BTW, im moving this thread to the Technical forum where it belongs.
It takes 43 muscles to frown, 17 to smile, and 3 for proper trigger squeeze.
The latest caliber or gear is no substitute for experience and skill. Rifles and cartridges don't make hits -- shooters do.
Fact of life:
After Monday and Tuesday, even the calendar says WTF!
