First time poster......
I've been reloading 40 S&W on a single stage press for a few months now, and I've gotten the hang of producing pretty good target ammo. However, when I first started, I had several FTF's. After taking a closer look at what I was doing and how I was doing it, I realized I was crushing the primers at times (although I read Mr. Lee's book telling me not too

).
Now, I still have 8-10 loaded rounds that have FTF (and yes, I've tried to fire them more than once with no results). I have a bullet puller on order, but this brings me to my question:
Is it safe to deprime those cases once I remove the bullet and powder? Is it going to go "bang"

?
Thanks for putting up with a newby.
