Those are mighty hot 158 gr loads, I'm not surprised you are having problems in your gun. I find Sierra lists loads that heavy using their jacketed bullets but I would be very hesitant to fire them out of an N-Frame S&W let alone a Taurus. Alliant has a silhouette load using the 158 gr jacketed bullet with 12.0 grs of Blue Dot but I'm guessing it, like the max Sierra loads, is designed more towards a T/C Contender than a revolver. The above loads also call for a CCI-550 primer which is different from the one you are using which could also account for a difference in pressures. I would back off the powder charge to under the 10.6 gr of Blue Dot suggested by most other sources I've looked at, including Alliant. Any finished rounds you currently have would best be taken apart and the components scavenged as they are dangerous to use. Same goes for your 180 gr load, stop using it immediately as the heaviest loading I can find for revolvers is well under 10 grs, again excepting a silhouette load meant for a much stronger frame. Follow the same advice as above regarding finished rounds for the same reasons. The 110 gr load may be within the suggestions of many manuals but it is evidently more than your gun can safely handle. I would adjust the die to seat the bullet to the suggested depth as that is a factor in developing safe pressures for that load. I would also start at the beginning load listed or 10% under the listed load and work up. Not all guns can handle the maximum charge and one can only find out what is safe for their gun by working up from the bottom. Reread your manual regarding safe operating practices or buy a manual that describes how to begin if your source does not have them. Starting out at the top is fraught with problems as you have discovered, fortunately not to the detriment of your health. As for the heavier bullet weights, go back to the manual and start at the bottom along with having the correct OAL. Plus, be aware that your gun has been subjected to tremendous forces which have the potential of causing damage or fatigue to it. I would strongly recommend having the gun checked by a competent gunsmith to determine if the gun has been unduly stressed, possibly damaging important parts or even making it unsafe to shoot.
