    Hi everyone. I sent my model 500 back to S&W due to forcing cone erosion. Just got it back. They seemed to recut the forcing cone now that the forcing cone looks different than it was before. But now the forcing cone is uneven all around the inner surface of the forcing cone as the picture shows. It's obvious if you look at the forcing cone from the side. Is this forcing cone still in good shape? Or should i sent it back to factory again? Thanks!

    It is hard to tell without illumination of the inside of the barrel. Also, it may be self limiting, i.e., it may stabilize at that point (wherever it is) and stop. Any time you pound a large bullet under high velocities, pressure, temperature and friction through a hole, you are bound to get some microscopic erosion.

    Here are two pics with illumination in the barrel.

    It looks to me like they set it back to the point where the rifling begins and then reamed it some what smooth. While that may work OK it could affect accuracy, so I wouldn't be too happy and would call them and have them put a new barrel on it on their dime. After all its an expensive revolver and has a lifetime warranty. BTW how many rounds are down the pipe at this point?? Factory or hand loads?
    JMHO YMMV

    i am having a hard time seeing really any difference. I'm by no means an expert though.

    Let me know if you need me to take some shots of my forcing cone and post them on here for you to compare. Not sure if that will help you at all.

    Thank you for the replies. I have put just over 1000 rounds through it. All factory full magnum loads.

    It does look like when they re-cut the forcing cone they set it back into the rifling. That would be unacceptable to me especially for such an expensive revolver.

    I never took a photo of mine but I just saw this on the gunbroker web site and thought of this thread.

    You can clearly see the rifling doesn't start right at the beginning of the barrel on the "stock" gun. I can tell you that when I had the problems with mine they replaced the entire barrel so I'd send it back and ask them for a new barrel.

    BTW, in this photo, is that flame cutting on the frame above the forcing cone?

    Despite the barrel being set back, it doesn't appear that they have set it far back enough to affect the rifling per se. I took the revolver to the range, they shot just fine. The distance between the throat and the rifling is decreased, but wouldn't that acutally increase the accuracy? Since now the bullet gets to spin a little earlier in the barrel? Please correct me if I'm wrong. How would it affect the accracy in a negative way?

    Yes. Quite common. According to our metalurgical experts, the flame cuts so far, then hardens the steel to where it doesn't cut anymore.

    Good to know, thanks. I was just looking at mine and it looks very similar.
