870 super mag

[SeaBreeze]

I got an 870 super mag a couple of years ago from my wife for an anniversary present. Has anybody else had trouble with it jaming and not ejecting the 3&1/2 's? Cost me a couple of deer this past year and a load of ducks and swan the past couple of years. Also why would it of rusted the very first time i took it shooting woodies. I had soaked it in oil right after i bought it and a couple of days before i used it. I ended up having to paint it with rustoleum this year. Any ideas?
