What is meant by "extended chamber"?

[P7M13]

I was looking at getting a barrel for my High Standard 22LR pistol so I could have it threaded for a suppressor. Found one, it states it's "22LR Extended Chamber."
What does that typically mean: more freebore, or a longer leade ?
Thanks in advance for any answers!

First I have heard of it!

With the diet I've been on I've wondered if an extended chamber would help.

And I think you would know, too, with your vast knowledge.

Maybe Tornado Technologies would know.

My guess:

Some of the high velocity/light bullet loads have a longer than normal case length. These won't work in some tight or match chambers. Maybe they are saying they do work in this barrel.

That was my guess too. After my crude comment to tag this thread.

I've heard this before, referring to a slightly longer throat.

I think it's for when you reload and use one of the many vld bullets available for rimfire.

Nope, not on my bucket list....
