OK i have this posted in ask experts and reloading.

first pic is as far as that case will go there is a small piece of copper i dug out of the top of the strap and barrel

went to the range with a new powder and bullet brand, no i did not work a load up as i have loaded for this cal for some time now.
i did not load t the Max either.
i used win 231 10.8-10.9, cci mag primers west coast 240 FP copper bullet with new Winchester case. looks like my primers are flatten out, cases were hard to extract (very hard) 3 had split.
Rounds did not feel that hot I shot some from my desert eagle and it did not want to rack the slid back enough to chamber another round. So there not hot enough for that gun. I was using 2400 and H110 no problems. Could it just be the gun does not care for win 231[?]

    it looks like a gas cut groove, but I don't know for sure. A shaved jacket tells me it is a timing issue.

    I agree with the timing problem. Better have a close look at the end shake on this one before you shoot it any more.

    Is this one of the original mod 29 S&Ws perhaps? If so, you may have one of the guns they recalled that had the bad chamber. If so, they will fix it for free if you send it in to them. Or at least they used to, several years agop.

    Looks to me like your forcing cone needs to be chamfered as the edge is sharp causing the jacket to peel. I have had this problem with two S&W revolvers using plated bullets both peeled plating in the same spot. I chamfered both and the problem was solved. This could very well cause higher pressure as well. It does look to me like you have some gas cutting on the top strap.

    Top strap cutting from gas. usually caused by faster burning powder and hot loads. I didn't check the load to see how hot it was. The 44 is a large volumn and I like it filled a little more. I go with a little bit slower burning powder like unique and blue dot I save the 231 for the amaller case capacity autos. The primers didn't look to be excessively flatened but with the hard extraction and split cases it sure sounds like pressure issues. The jacket pealing is another issue. Hard to diagnose on line. I would take to to someone who works on revolvers. If you don't have one close by contact me direct.

    I HAVE ALMOST ALWAYS USED UNIQUE AND 2400 till i got the DE 50AE. then started useing H110, but this gun has not seen much of anything but 2400. i think it in the mid range for burning rate. i loaded up some with the win 231 i found on sale..
    IT MAY HAVE BROKE MY LITTLE TOY[:(]

    Shaving problem , caused by the cylinder being out of time as others have said..Or just a worn cylinder stop..

    Stick with the Alliant 2400 for .44 mag as it is the best..

    I think the biggest issue is a timing issue. Recommend getting the gun looked at to fix the problem.

    Also my reloading book has a max of 10 grs of 231 behind a 240 gr jacket bullet. I think you are on the hot side.
