Crossing the transonic region never helps precision and usually degrades it so most if not all match-grade .22 ammunition is subsonic.
It's not advertised in bright red letters but competitive shooters (who know their butt from a hole in the ground) are aware that not flirting with the transonic region is better for precision.
