I have a new Contender barrel in 223, and I have had this problem since I purchased it. When I load a cartridge, if I don't carefully line it up with the extractor, it jumps over the extractor into the chamber. When I close the action, the extractor pops into place on the cartridge, but most of the time the extractor jumps back over before extracting the fired round. There is obviously something wrong here. All my other Contender barrels are for rimmed cartridges, so this isn't a problem. This is the first Contender barrel I have used for rimless cartridges. What part is broken/bent/missing?

Ken,
Just bend it up a little.

I took a little time tonight and discovered/fixed this problem. I removed the extractor (hard part was finding a punch small enough to drift out the pin). I then discovered that the extractor was not straight. I cleaned and straightened it, cleaned out the extractor "housing", and also increased the tension on the leaf spring by increasing the bend in it. I then reassembled it, and it now works like a Swiss watch. Before now, for some reason there was absolutely no spring tension on the extractor (I didn't even know a spring was in there). So, the problem must have been the extractor was bent or the spring was not positioned correctly. The center of the extractor was arched up.
