"So is “ordinary target ammo” subsonic and have similar power?"

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.

I could not agree more.

The main value in this thread, IMHO, is passing on the accumulated knowledge of yesteryear to the newbies.

Some of it is subtle, but very significant.
