It wouldn't matter if you necked down a 55-gallon drum to .22 - you'd only get 4500 fps or so. You can only move so much gas down a .224" bore in a few microseconds, all the rest is wasted or used to burn that bore.
Also, to keep from making the thing a bomb, the powder would have to be two steps slower than Kingston briquettes.
And THEN there's the problem of the bullet. They have an annoying tendency to simply vaporize when they're spun that fast, booted that hard and heated that much.
