There's an older fellow who has videos of himself shooting clay birds from the hip.
He rarely misses them.
On the other hand, the last time I was at the range, there was a young fellow trying it, and he couldn't hit a stationary, 30" square cardboard target, from 25 yds.
Like most things, how successful it is depends on who is doing it.
