Without seeing the gun, impossible to say but I doubt it.

Break the rounds down and get a oversize 40 or 45 cal bronze brush and scrub out the cylinders.

If you are reloader, resize a 357 case, slightly flare it a little over so it's hard to put in the cylinders, tap it in each one with a mallet. This will act like a scraper and clean out any carbon build up if a lot of 38's had been fired in the gun. Then brush it out and clean with solvent.

Load some new 357 or even buy a box of regular Rem or Winchester, whatever and try them. The BB is full house + loads.

I had some stick in my M&P R8 (M327) the other day and they were light Magnum loads, turns out the brass had split and was at the end of it's reloading days.
