Hi Joe,
Hmm, you might need one of the newer extractors Remington has put out for
http://www.rimfirecentral.com/forums/ and ask your questions on the Remington forum over there (more knowledgeable 597 people there). I unfortunately can't help you, I have an older model 597 that performs flawlessly for me.
# When I first bought the rifle about 6 weeks ago, I noticed that it had # a terrible tendency to jam. What would happen, is that the spent cases # would wedge the bolt open, preventing the action from feeding another # round. I brought this concern to this NG and many people said that the # rifle had to be 'broken in', and others said to try ammunition with a # 'higher energy'. I believe that I have exhausted both of those # efforts, as I probably have about 600 rounds through the rifle by now, # and switching to CCI Velocitors has made little to no difference. I # believe the problem now is more of a mechanical issue with the gun. # This constant jamming happens quite frequently and has really taken # away from the enjoyment of shooting it. If anyone has any information # about this rifle in particular, or just general advise, it would be # greatly appreciated. # # By the way, I don't want to hear any comments such as 'You should have # bought a 10/22'. I like the Remington just fine, and it would suit my # needs quite adequately if not for the issue of it jamming.
