Large Shank/Small Shank

How do I determine which is which?

A large shank has a step after the threads and a small shank doesn't.

First picture is the difference

This does not hold true all the time with factory barrels. my F/TR 308 factory barrel is large shank and has no step. the best way to find out is actually measure it and the second best way is use the nut method.
