For AWG 22, it's going to be at or below 70 Ohms. For instance, MIL-STD-1553 implemented as a shielded twisted pair is around 72 Ohms, and they do something extra to make it a "controlled-impedance twist." Something like 300 Ohm twinax, where the wires are held apart a set distance, except the distance is much less.
