Paulie, the barrel stubb, or "thingy" as many of us call it, is nothing more than a piece of barrel, about an inch or so long, that has the very first part of your chamber established in one end, just to where the shoulder is complete, with the other end faced dead square.
The two main uses are: To use as a 'bump gage' in conjunction with a set of dial calipers when arriving at the exact amount that you are moving the shoulder back during the resizing proccess, and as a means of finding where the bullet ogive is contacting the lands in a loaded round. Keep in mind, with tyhe second, this is just to give you an idea, as this represents the throat and lead angle in an unfired barrel. You can keep moving the bullet in or out untill it either shows a mark or doesn't as you insert the loaded round and "twist it" so the lands scribe a circle around the bullet's ogive..........jackie

I assume you are referring to the tool a smith makes using the chamber reamer. It is faced off on both ends, and the reamer is run in at least to the shoulder. It's main use is to check should bump back when sizing. It can also be used as a quick check to be sure your loaded round is small enough to fit in the chamber (tight, fitted neck). And while your barrel is fairly new, you can use it to set your seating depth. Handy little things. Ha! Jackie beat me to it!
