You can read all the articles you want but it doesn't disprove what all of the bench rest shooters in any national event know to be a fact. I guarantee if you go to a bench rest event- where a few thousandth's of an inch can mean winning or losing a match - they will be shooting subsonic ammo - every last one of them. And 22 rimfire ammo is especially sensitive to it due to the poor ballistic shape of most 22 bullets.
I guess there is one answer to this problem- shoot hypervelocity ammo that doesn't drop below the sonic barrier before it reaches the target. The problem is no one loads accurate or competitive hypervelocity ammo..
