    As a new gun owner I chose a new S&W model 10. Just fell in love with it.
    I live fire practice almost weekly, using jacketed bullets of the standard .38 special cartridge. I always clean after each session (usually 100 rnds), using a brass brush and/or a bore snake and CLP. I understand the cylinder drag marks evolving being normal, but I am more concerned with the cylinder bore demonstrating a ring of ?wear near the barrel end of the bore. Is this concerning? Am I not cleaning properly? I just can't recall this being present when I first got this great revolver. Comments or answers? Thanks.

    Welcome to The High Road!

    Was the gun clean when you first looked at it? You may just be seeing the shoulder that marks the end of the chamber.

    Welcome to THR !!!

    Your looking at the business end of the cyl. & it`s more than likely carbon build up .

    Remove the cyl & soak it in kerosene or diesel for 24hrs & scrub it now & then.

    There are precious few .357 Model 10's out there. If you have a 10-6 it could be carbon/lead buildup from firing .38 in a magnum chamber. If it's a .38 special chambered gun (a "new" Model 10)and the cartridges drop in cleanly I'll wager it's fine.

    As far as the cylinder bore wearing out? S&W revolvers have a great service life. Your grand-kids will most likely still be shooing it.

    I think it safe to say that there are NO .357 Model 10's, at least from the factory. I think Sport 45 is correct and that the OP is looking at the shoulders in the chamber. Those are made to be bullet diameter instead of case diameter, so that there is minimal gas escape as the bullet leaves the case.

    Cleaning the chambers (what the OP calls the "cylinder bore") with a bronze brush will remove leading and crud and the chambers will be shiny again. If there is a lot of lead buildup, a Lewis lead remover should take care of it.

    I always thought the Model 10 was .38 and the fixed sight blue/nickel .357s were Model 13s. I found the above reference on a 10-6. Also, found an older thread on this. Would like to see one.
