I don't know if I would call this a failure or not more of a reloading issue. I have a 358 FWT that if I set the primer just a tad to deep the firing pin won't hit it hard enough to ignite the primer resulting in just a click and no boom:)
That is not the first time I heard that about 358's. It can happen with any of them and I think that's the reason they stopped making them.
We don't seem to have any checklists to go through, magazine boxes that bind, actions bedded on top of mag boxes that must be ground down( That one really cracks me up. Must be some sharp bulbs in those plants) screws too long, firing pin protrusions set by a set screw glued in place.......geezus.
Very little breaks very often.
Actually the only commonly available rifle I'm familiar with that seems as durable is a Ruger, which take a lot of abuse and never seem to break,even though they sometimes do not work as well,and sometimes need more tweaking to shoot. Still I trust the things pretty well.
