I have an Ithaca SKB Century single barrel trap gun. I really like it and shoot it well, but recently it began misfiring a shell or two per box (they all fire on the second try). Does anyone know where I might get a new hammer spring or know a gunsmith who could make a new spring and repair the gun?

A good place to start would be to take the bbl. off & using a piece of hard wood or delrin held firmly against the standing breech pull the trigger and then measure the amount of firing pin protrusion, it sould be a minimum of .040 inch for good ignition. Also look at the firing pin's face [end] to see if it shows any signs of pitting or errosion. If the protrusion is less than .040 the problem could be accumulated gunk & powder build up on the action's inside holding the firing pin back from the inside. Take the buttstock off & give the action a through soak/cleaning and then relubricate; methods for that were just discussed on another recent thread.

Another possibility could be 'hard' primer cups in the ammunition you are using. In any case, if the gun has a lot of rounds through it or its history is unknown a good strip & clean will be beneficial w/no harm done at all. Any qualified gunsmith should be able to do that for you if you are uncomforable doing it yourself.

I would be surprised if the problem is the hammer spring, but it might.

For SKB info, I would contact Chris Schowler(sp?)w/Eagle Trading; they are an advertiser here & he is a good guy to do business with.

kind regards, tw

Bill, Talked with Ron Sharp today and mentioned your problem. He said 9/10 times this happens its the cocking foot spring. A small spring, either broken, wore out of gummed up. Ron's phone number is 905 774 6368.
