That's a pretty lousy crimp for factory ammo. I haven't shot factory ammo in my .357's for years, and I see now reason to start now from the QC I see.
I can second that motion....I had Remington GoldenSaber 125-gr jump crimp on more than one box. I tried a number of boxes and it was the same. I just do not use them in my 340PD or M&P340. I use the Speer 135-gr for short-barrels and have not had a crimp-jump yet. Good luck and find yerself a good round and stick with it. Shoot safe....It's best to use cartridges having bullets with cannelures. I've had the same experience with factory Remington 125gr Golden Saber rounds shot from my M&P 340.
Sorry if this sounds like a dumb question, but what is meant by a bullet with a "cannelure?"

I'm surprised that the instructions that came with your gun didn't warn about this. I'm sure my 325PD instructions warned about testing for this, and probably 342PD, as well. Neither of those guns is as bad as .357 Mag in an AirLite.
I carry Remington .357 Magnum 110gr SJHP ammo in my 13.3 oz M&P 340. It's accurate, with manageable recoil, and zero bullet jump.
I would just about swear that mine is marked no less than 120 grain bullets....that was to prevent cylinder face erosion I presume?
Only the titanium cylinder models are so marked. The steel cylinder models like my M&P 340 have no such prohibition.
Yes. It's to prevent erosion of the titanium cylinder.
Thanks,
I keep forgetting that there are a few of the 'airlite' guns that have stainless cylinders.
