    I unscrewed my choke out of the barrel and found some damage to the threads of the choke. Here's my question; Is the choke made of a softer metal than the barrel? I'd like to know if the threading within the barrel is harder and therefor probably not damaged. This is on an SKB 85. Thanks, Jim

    What kind of damage? Are you talking about the 3 or 4 threads at the chamber end of the choke that appear to be flattened? That's normal; the manufacturers do that before the choke leaves the factory. Keeps the carbon from gas leakage from building up in those threads and locking the tube in the barrel.<center>

    Nice pic, MK. I've honestly never noticed that on my chokes. Going to have to check when I get home.

    Ya, you're right. Great pic you got there. Upon further inspection I guess I have nothing to concern me. Darn choke unscrewed so hard out of the barrel I guess I was 'expecting' to find something looking wrong. Thanks, Jim
