I assume the rifling twists, but at what rate and how deep is the rifling?

I have shot and shot at a lot of LBJs (little brown jobs (birds)) with .22 shot in rifled barrels, and I have patterned some varieties of .22 shotshells. I can say rifling really tears up patterns relative to what is possible with smooth bores, so I am interested to hear more about these raye barrels.
