Is it my imagination, or does that cylinder lack throats?
It looks as if it were bored straight through at the diameter of the cases.

S&W did release some K-frame M66-8s (spring of 2017) that had undersized forcing cones of which mine was one.
I found it before firing it & fixed it myself.
Maybe your L-frame has the same trouble?
Demon775; could you do a quick/easy check to see if yours are undersized?
Open the cylinder of the unloaded revolver.
Grab one of your fired/empty 357 Magnum cartridges (a sized case is better) & try to insert the mouth of the case into the forcing cone of the barrel.
It should just enter into the FC (assuming the case isn't over-expanded from chambers that are too large).
If you have a .357 bullet you can do like in my pictures below.

Do not fire that revolver until you receive it back from Smith and Wesson.
As noted by others, one or two charge holes are not properly timed indicated by the off center primer strikes. Trying different ammunition will not correct the timing issue. It will only subject you to possibly being injured by a shaved jacket.
Send it in for repair.

IMO, it is too bad that you hadn't taken an image of the cylinder immediately after firing, that had all of the brass still in place. That might be able to ID one or more cylinder chambers that strike poorly. My best guess is faulty cylinder alignment (poorly drilled or a poor bushing installed). I observed ~7 of the 14rd were noticeably struck off center.
FWIW, Fiocchi is my go-to commercial ammo for my .357s especially in my two 686NDs. I have never had an issue with this brand.
