Thanks Guys!
I'm still not sure what happened. I'm new to reloading and I started on someone elses equipment and all was OK. I then used my own stuff but his RCBS 30-06 dies. That was OK too. I have since aquired my own used RCBS dies and the newly formed cases chamber very tight...hard to close bolt! In my ignorance I bought small base dies (for autoloader) which should be looser not tighter. In the mean time I went ahead prepped and primed a bunch of cases. I'll get some different dies and see what that does.
If you set up the size-die correctly, perhaps your loaded overall length is too long?
