I think he was feeding me the "tight chamber neck" popular theory they help center case necks in chambers. In spite of the fact that 99.9% of all loaded case necks they're made tight for are are smaller in diameter than those tight chamber necks are.
Sierra Bullets' first ballistic technician (bless his departed soul) tutored me on case to chamber fit for best accuracy. His byline on case to chamber fit is oft times repeated by those who knew him well:

Lots of clearance from body and neck to the chamber. He full length sized all the cases used to test their bullets for accuracy. Their 168 grain Int'l match bullet was the first 30 caliber bullet to frequently shoot in the ones; group after group with 10 shots each at 100 yards.The case has to fit the chamber like a terd in a violin case.
