It probably just needs a good cleaning, but one of the guns I got in my new collection is a nice Winchester. Heavily used but in great shape.
It doesn't chamber the 3rd shell. I will give it a good cleaning and oil and see if that helps but let me know if this is a specific problem for this gun.
It seems to be a popular field and military version.
 
The previous are answering if your question was: won't accept third round in the mag. If it won't feed the third round from a full mag, then look at the mag spring.
 
Zippy brings up a good point that will require your clarification. Are you saying you can't get a third shell into the magazine or are you saying that the last shell in the magazine doesn't go into the chamber when you pump the action?
 
I was a little premature in posting. The mechanism is different from any of my other shotguns. I think I just need to get familiar with it.
Yes. The duck plug was in preventing the 3rd shell from going in but it just seemed wrong somehow.
I thought the carrier wasn't right. It seemed to be loose but it actually locks in the down position and loads the next shell perfectly.
