Reaming forcing cone, how does this look?

[zomby woof]

GP100 .357. I've got the Brownells forcing cone reamer. I think i have to go more. The lands look like they're originally cut very far up. Do I have to just touch the lands, go a little farther?
How does this look so far? What is the maximum diameter of the opening?

Nice and smooth.

Much more important - how does it WORK?

Mr Target knows the answers and is never wrong.
