Thanks Alex.A clicker is a tight case that is stuck in the chamber. The bolt makes a clicking sound when the extraction cam pops the case free. In normal use, your extraction cam is not used.
Most of the time they are caused from an interference fit at the base of the case and chamber. The main cause of this is a sizing die that is oversived in that area. They typically wont show up until 3-5 reloadings of the case.
IME, there are several causes of clickers. If farther forward, where the die is sizing, it is just no sizing enough.
...but what if it is below the die in the web...do chambers need to be tight down to the web, but some amount oversized below the 0.1 line? Are case webs accurate enough across the lots and multiple suppliers to cut it within the springback allowance? Is this also hampered by our desire to run these things at 65000 psi without test equipment?
