While this has nothing to do with FTF and light strikes, maybe it will drive home the practice of tossing a round that has been chambered a few times.

The round on the left was chambered several times until it just didn't feel right. When I unloaded it I was very thankful I didn't fire this round.
While this maybe attributed to a bad crimp as the one on the right didn't require much force to set the bullet back, it still tells me that repeatedly chambering a single round is not good. It also told me I need to shoot more.
