I would say it depends on how you pull them and if they were crimped. I have pulled down 200 45acp rounds after having 1 squib when I started reloading . I pulled them with a kenetic puller and did not deprime them or resize them. Pulled , recharged correctly and reseated the bullets. Ended up finding 9 more that had no powder , meaning I missed a whole row on my tray. I no longer watch tv while charging cases.
