Bought my remington 870 Shorgun new a few months ago and it has given me ejection problem with field loads jamming up the gun and failing to eject and have to remove the barrell and push the shell out with a cleaning rod. I dont even have 100 shells through this gun yet. Any comments! Has happened twice and the first occurrance was on the first shot fresh new out of the box. Seems like the shell casing expanded so that the single extractor could not pull it out and toss it.
