The record group today is about 5" smaller than that one.
So its taken thousands of good shooters shooting hundreds of thousands of record rounds with the best possible equiptment to accomplish that.
And the group can still be measured with a carpenters tape in inches and fractions of inches.
The idea of a custom die using the same reamer that cut the chamber originated a long time before John Widden. Many of those shooters used them and still do.
Have you ever sat and watched a cat chase it's own tail? lol
