Dont know where to go from here. I purchased my M2 6 weeks ago and use primarily for waterfowl. I have put over 400 rounds through it , 3" #3 1 1/8 Kents, and still have jamming issue evertime i go out hunting. I clean the gun very well after each use, well lubricated rails , cleaned the plunger in buttstock, tried everything this forum has listed for problems. I am very frustrated . Whats weird is it doesnt seem to jam the same way every time. Ive had FTFs, Failure to eject spent hulls, and this last time in the blind on my 3rd shot it did not fully chamber the shell and i had to push the bolt forward to finish the cycle. Have a trip scheduled to Arkansas in 2 weeks on a guided hunt. No way I can send it in and get it back in time. I purchased this 1300 dollar shotgun so I would not have these issues on this dream hunt. Very dissapointed to say the least. Does anyone have anymore suggestions that I can try to figure out this problem without sending it in?
