The last two times I went to the range to fire my evil black assault shotgun, when I load the magazine to full capacity (8 shells), the spring will somtimes bind up. I'll fire the first shot, then rack it, and no shell springs out of the magazine. When I clear the chamber and look, I see that the remaining seven shells are sliding back & forth freely. The last few times this happened, I simply unscrewed the magazine cap & stuck something long & skinny down into the magazine to try to free up the spring. That works until the next time the spring binds up.

Any idea what is causing this, and any ideas how to permanently fix this? The guy at the range said "Only put seven rounds in the magazine," but I want to be able to load the full eight rounds.
