If a "factory spec" case, i.e. something that was full length resized in a die that was set up correctly does not chamber, you may want to get a gunsmith to have a look at the headspacing. It only takes a couple of thou for a case to be too large to close the bolt, but it may also be something more serious....

While everything you said is correct you(he/she)dont/ doesnt actually need to go buying anything.
A little common sense and logical thinking will sort it for minimum outlay.
