I don't believe the primers have pin holes. The primers have split due to excessive space in the case pocket. This can be caused by excessively large case pockets, or undersize primers...... Or both.There is NOTHING wrong with how these primers seated, your primers all have pinholes in the radius…look at your own photos.
