If you'd like to, I'd be happy to meet you on a server and help you out.
The key to chambering is reading animations and having fast reflexes when you recognize what is coming at you.
It's largely timing so you're going to eat quite a few swings before you get it down.
Don't duel the same person over and over, either, if you're going to just be practicing chambers. Different people have different timings and you need to learn to be able to adapt on the fly.
As Antigone said, be sure not to force a chamber when you're coming off your back foot or you're in an awkward angle/position. I find that I get in the most trouble when I "force" them, chamber blocking shouldn't be forced, it should be something to supplement your style that you pull out when you see something coming that you can safely chamber. Think of it this way: Only swing for the homerun when the ball comes in slow and easy over the plate. Implement chambering into your style depending on your level of agression, but, in all honesty, beware of becoming too predictable with it. With respect to Mad Dawg, even though he's learned chambering pretty well, he's pretty easy to beat because he relies on chambering almost exclusively, and while chambering is an advanced skill to use, it's pretty easy to counter by using slight holds. Only the very .5% of players will be able to adjust to holds on the fly.
I have a lot more random nonsense I could dump into your head so your brain can eat at it while you're working on chambering.

Also, I've found that when you're first learning to chamber well, you need to stick to learning on one weapon speed. Don't jump between medium and fastest until you get it down solid on one speed, and you'll be able to learn all other speeds quickly. It's really just kind of a "ratio", if you will, that you get down in your head and you can adjust to speeds easier. Like I said, a large key of it is recognizing the animation and swing coming at you before it hits you, then largely it's simply timing. Chambering is a pretty scary and ballsy thing to do so it's easy to get nervous/scared/excited when you first start to learn it. Just stay patient and "be water, my friend." BRUCE LEE STATUS YO
If that doesn't work, sometimes I like to get naked, cut open some watermelons and put my feet in them as I play. I find this helps chambering effectiveness.
