I can see where the subsonic has the advantage at rimfire BR distances, 50-200 yards or so??
Now we have long range steel shooting where the distances go much further. I can see where the faster 40gr ammo can have an edge in atmo at those distances.
I've shot plenty of federal bulk 36gr out to 400 yards or so plinking at rocks, pinecones, etc. It definitely doesn't tumble. Maybe elevation is a factor too. What is stable at 4000', may not be stable down by the sea.
