Took my M1 combat out for its debut yesterday, and was dismayed at its failure-to-eject's. I used Remington 00 2 3/4 buck law enforcement reduced recoil and the Benelli failed to eject any of the 25 shells properly. I also tried #7 birdshot from Remington and it did much better with only about 2 shells failing to eject properly. My question: This sound right for a first time out? The manual mentions a "break in" period, but this experience seemed a little odd, especially for a shotgun with such a great rep.
