One would have a difficult time using a SAO revolver in bullseye rapid fire stage (5 shots in 10 seconds), but with practice it probably could be done. I believe the SAO was intended for use in some competition other than bullseye, but I don't know what. It probably wasn't Cowboy Action. I don't know if it would even be "Legal" for CAS, but maybe it would.

Back in my long-ago bullseye shooting days, I did use a K-38 in the centerfire stage.
