First time using lee collet dies and didnt have them adjusted properly so i pulled some bullets and resized the case neck and in the process deprimed cases. Can I still reuse the unfired primers that I popped out of the cases.They dont look crushed or anything.
I've reused primer like that on occasion and never had any issues at all they always went bang. I generally set those few primers aside and use them for plinking ammo instead of hunting or SD purposes.
I have re used them a few times with out a problem. I would think if they end up as duds it would be from the repeated handling and the oils from your hands that would contaminate them rather than simply pushing them in and out of the case once.
As long as the primer isn't deformed in any way,you can re-use it.
I can't count how many primers that I've knocked out and reused in all the years that I've reloaded.I have never had a dud because of it.
