Alright guys I'm still a newb to marlin 39s and have added a new one to my quickly growing collection. This one is an early model octagon barrel serial # 101xx. I took it out today to test fire and it is failing to feed. When I work the lever to feed the shell jams like its not lifting all the way to feed into the chamber. Like I said I'm still learning and need some help troubleshooting please. After initial test I took it back inside broke it down cleaned it completely and tried again with the same results.
