I ordered a Volquartsen Extractor for the 597, installed it this afternoon and took it out for a test run. It worked flawlesly! I fed it all kinds of 22 ammo I had laying arround, good stuff and cheap bulk plinking ammo. I even fed it some I found laying on the ground! The gun fed it and fired it!! I only have one question, why can't Remington produce an extractor that works for this rifle? I've read on several other sites that this is a common problem with this model? I really like the look and feel of this gun and it groups fairly well out of the box.
