Well, you aren't supposed to have one in the chamber. In fact, for all that is Holy please DO NOT measure your bore with a live round in the chamber.
Yes, that seemed like a highly questionable idea to me.

UPDATE:

I was talking to a gun shop owner (long time shotgunner) and he gave an excellent reason for why 18.5” vs 18” and how it is measured.

Yes, another person here was correct (mostly) the correct way to measure is from barrel end to the bolt face with breach closed.
And yes a “Rod” can be used, but not generally how it goes.

Now here’s where it gets interesting ....

Legally speaking 18” is the minimum length BUT !

Let’s say you’re out hunting or shooting or whatever...
and some type of law enforcement officer wants to “inspect” your gun. He’s likely to use a tape measure and run it down the barrel to the bolt face .....

Now if the officer doesn’t like you ... he can “flex” (bow it inside the barrel) the tape measure and suddenly your 18” barrel is 17.5” and you’ve got trouble. I.E. he has probably cause to search you car, truck, home, whatever and you’ll likely need to go to court to get your gun back ... and if the Judge is anti-gun , you have real issues.

The 18.5” barrel gives you a safety margin making this trick more difficult if even possible. So while 18” it technically legal ... a bit longer could save you troubles.

For a Home Defense Shotgun the desired end result is a one trigger pull threat stop.
A good low recoil buckshot has the recommended penetration at home defense distances without over penetration.
Good buckshot placement and patterns enable the one trigger pull threat stop. Your barrel should have a point of impact within 12 MOA of point of aim with slugs to get reliable hits, approximated by 3 inch slug groups at twenty five yards.
Your barrel should pattern well with the buckshot you use. Patterns of 4 and 8 inches at seven and fifteen yards will be tight enough for good center mass hits without collateral damage from stray pellets. If you plan to “point shoot” at under 15 yards then train with a bore laser that fires when struck by the firing pin. Otherwise you need a good sighting system with a low light advantage. In the end, it’s a question of what is the desired result rather than what is the best shotgun barrel for Home Defense.
