I wonder why they don't make medium bore air rifles.
They do, but they're as expensive, if not moreso, than medium bore centerfire rifles. They tend to be custom guns. I can't remember the guy's name, but there's a custom airgun builder out there that makes airguns up to 50cal and has used them to take buffalo. The Korean guns Harold Tuttle mentions are nice too.
My biggest beef with the larger caliber airguns is that you need to shoot them at regular firearms ranges with firearms backstops. They cost about as much as a firearm and are nearly as loud. What's the point unless you're just an airgun fan?
Just saw Rabbit's post, that's a new gun to me. When I was "into" airguns, it wasn't around, at least in the US...

What I'd like is a HANDY, powerful air rifle. Quiet would be nice, too
The BSA Supersport .22 I used to own was styled like a standard rifle and was fairly powerful. It was tackdriver accurate and had a very nice adjustable trigger. It was a springer, so you needed an airgun specific scope or a high end centerfire scope, not a cheap 22lr model. Price when I bought it in 1999 was $170ish, I'm sure they're more these days if you can even find one (I think the only importer went out of business). It was quiet enough to shoot in my basement without bugging my wife upstairs, but not so quiet that I could shoot it in my towhhome's backyard.
Since airguns over a certain power limit require a firearms certificate in GB, they have two models. Being a resident of the US, I had the FAC version: http://www.bsaguns.co.uk/?ID=53&ProductID=579
