Mehavey, I understand what you are saying, but with a factory round they chamber fine, I am also able to chamber my brass fine with no primers installed...
I found this thread online in my searches...

This is the identical problem I am having...
So I will first try a new priming tool from Lee and if not, purchase a uniformer...
I do believe after all my research, that with a controlled feed bolt primer depth can be an issue for chambering..
Thank you for your reply...
