Thread: re-using primers

I have a mate who has sold one 223 and purchased another.
He has quite a bit of sized, chambered fire formed brass that has also been primed for the sold rifle.
The prepped brass won't chamber into the new rifle so he has to re-size the brass back to standard factory again.
He asked me if I thought he could re-use the popped primers again once the case's are re-sized.
I have done a bit of reloading but never had to do this so hence the question .
Do the primers distort or damage when removed and are you able to put them back into the primer pockets without the risk of misfires or other problems .
