    Anybody know what would cause the chain to wear through the gear like this?

    Improper tension will cause premature wear there. That looks pretty extreme. Sure you have the proper pitch chain?

    How many chains has your saw been through on this sprocket? They are considered a wear item. Oregon suggests replacing the sprocket every two chains. I usually get more out of them than that, but it's a place to start, I guess. If you feel it's premature wear, Wood Wolverine made good suggestions.
