I've never seen any in 22 cal, but my grandpa has shot several hundred in 30 that look very similar.
They were a Herter's bullet, I think they called it the Wasp Waist?... They are extremely accurate out of his '06 and his 300 win mag.
One claim for the wasp-wasted bullets were higher velocity. With less metal in contact with the bore there is less friction than in a "standard" bullet of similar size and weight.
My grandpa told me they were supposed to get a little higher velocity and less fouling. All I know is I wish he would sell me the rest of his stockpile, he still has about 2500. He still has not found a bullet that shoots as well as those do in his guns.
