I segregated all of the Win brass and processed them separate. Unfortunately, over half of my 9mm brass is Win so it can be hard to find these problem children that got mixed in.

.357 posed a bigger problem. I am using my RCBS dies from probably the late 1970s. The size die and the seating die require too precise an entry into the die for progressive use. I can rotate a single round through the stations without a problem, but if the shell plate is fully loaded I start crushing case mouths.

I already resorted to a paper clip for the spent primer chute. It started hanging up and spent primers knew exactly where to go to jam up priming.

Some of these problems can be addressed by decapping before loading. I decap on a single stage. When I feel a stiff primer I ream out the pocket with a handheld tool. Just takes a second. Not only does this catch the crimped primers, it keeps a lot of mess and trouble away from progressive press.
